Named Monsters In A5E Rulebooks

The following monsters are named in Level Up rulebooks.

• Adraxa ( Titanic Dragon Turtle ; Monstrous Menagerie). Sailors speak in hushed whispers of Adraxa, the luminescent, emerald-studded Queen of Dragon Turtles who dwells on the Elemental Plane of Water. Twice the size of most dragon turtles, she has ruled oceans and sunk entire fleets.
• Aklea (Empyrean variant; Monstrous Menagerie). Wild berserkers revere Aklea, a mighty daughter of a war god. In a battle against rival titans, Aklea sought to protect a group of mortals but unwittingly slew her charges while in one of her blind and unstoppable battle rages. Aklea is said to wander the stars, slaying dangerous monsters and trying to atone for the harm she once caused. She searches for the peace and self-control that has eluded her for so long.
• Bronze Queen ( Medusa Queen ; Monstrous Menagerie). Once a leader among the original medusas, the Bronze Queen lives in a sandswept palace among the bronze statues of those that have hunted her, defying gods and mortals to punish her further.
• Echo Emperor (Unique Aberration; Planestrider's Journal). All of Luria functions under the gaze of a personification of the potent aura that imposes lawfulness on the plane. This entity speaks to the ruler of the realm (or whoever might best grasp power) through dreams and quiet whispers until a compact is agreed to and it takes over, rejoining the Council of Order (a quartet of forgotten gods with Lawful auras) and continuing its aeons of rule. Though the Echo Emperor may be slain it cannot be destroyed while Luria still exists, as certain to take control of the realm as the sun is to rise.
• Emperor, the ( Dire Tyrannosaurus Rex ; Monstrous Menagerie). “The Emperor” is the nickname locals have given a scarred, one-eyed tyrannosaurus rex of exceptional ferocity. The Emperor has developed a habit of raiding humanoid villages, and it has shown itself clever enough to foil traps and ambush hunters seeking to end its reign of terror.
• Fatespinner (Unknown; Planestrider's Journal). Somewhere in the Ethereal Veil, upon a plane of vast, silver cities of porous towers connected by silken strands, a great weaver works tirelessly on patterns of silk that tie one world to the next. Everything here is to her precise design, maintained eternally in axiomatic perfection. In every window of these webs, she sees destiny play out for every being who takes part in her plans, and as her web grows, so too does her reach. Here, Weaver of Destiny, the Mother of Law, Lady of the First Web, the Fate Spinner weaves patterns into prophecies and chaos into order.
• Gloriana (Unique celestial; Monstrous Menagerie II). As queen of the gods, Gloriana once held court from atop her radiant throne, dispensing blessings and justice to deities and mortals alike. Banished by younger, upstart gods, for millennia she languished in the dark void beyond the heavens, where she dwelled on thoughts of hatred and revenge. When restored to her true power, she vowed, she would use her divine sunlight to blast the world into a sterile desert, preserving only a small area of earthly paradise where her loyal subjects could bask in her presence.
• King Fomor (Empyrean variant; Monstrous Manegerie). According to myth, King Fomor was the leader of a contingent of empyreans that waged war on the gods. The son of a god of knowledge, Fomor used his third eye to spy on the counsels of his enemies. His rebellion culminated in the betrayal and murder of a god—according to some accounts, his own father. A divine curse twisted King Fomor’s body into a monstrous form, and he was banished to the fairyland of the Dreaming, where he is now counted amongst the foremost archfey of the Unseelie Court. He trades information for power and awaits the day he can return to the Material Plane at the head of an avenging army.
• Kraken ( Titanic Kraken ; Monstrous Menagerie). Some sailors have encountered krakens and lived to tell about it, but even old salts speak in hushed voices of the leviathan they call the Kraken. It’s said to be the first of its kind, created by doomed titans to be a spear thrust into the heart of the victorious gods. It is possibly the parent of all other krakens.
• Medon ( Demilich Mastermind ; Monstrous Menagerie). The powerful demilich Medon doesn’t molder inside a deserted tomb. Instead, he lets those who don’t understand his true nature carry him around. While inactive, the Skull of Medon can be used as a +3 wand of the war mage that, once per day, allows the owner to use the demilich’s Devour Soul ability on a target of the owner’s choosing. When the time is ripe, the Skull of Medon reveals himself as a demilich, devouring his owner’s soul and then flying to a spot where another powerful spellcaster can discover him. Medon has four soul gems instead of two, each worth 50,000 gp. Each soul gem acts as a soul vessel: when the demilich is destroyed, he can reform around any one of them. The Skull of Medon can be permanently destroyed only by defeating him, then destroying each of the gems.
• Midir (Unique titan; Dungeon Delver's Guide). The handsome son of a god, Midir once ruled an earthly empire. Midir’s love affairs were legendary and culminated in a romance with another titan’s spouse. This seduction led to a war that racked the earth and nearly brought down the heavens.
• Mouthless One (Archlich; Monstrous Menagerie II). Scholars whisper of the Mouthless One, an archlich who shares elusive secrets with those willing to pay the price. The Mouthless One’s only desire is for arcane secrets, and nothing is beneath or beyond this ambition: the Mouthless One has killed mages to gain possession of their research notes, toppled empires to win a closely guarded scroll, and even felled a god to plunder cosmic truths. When violent methods are impractical, the Mouthless One employs a network of spies or trades secrets directly with adventurers. But sharing information with the Mouthless One is dangerous. A creature that publicizes one of its secrets usually ends up dead, their mouth replaced with a smooth expanse of flesh: a grim warning to the Mouthless One’s other confidants.
• Morius (Unique Celestial; Monstrous Menagerie II). Once the god of death, Morius is now the reborn god of suffering. A gaunt figure clad in blood-rusted armor, Morius stands silently in his thorn-filled forest, observing the cavorting ghouls, vampires, and cultists that do his cruel bidding.
• Odagglath ( Chained One ; Planestrider's Journal). Commandant of the Angolin army’s chain devils.
• Queen Cir ( Dread Knight Champion ; Monstrous Menagerie). Queen Cir was a beloved monarch and holy knight dedicated to the sun god. When invasion imperiled her nation, she accepted a gift from a mysterious stranger: a magical sword named Legion. Anyone slain by this sword rose as a zombie under Cir's control. With Legion's help, Queen Cir slaughtered invaders and transformed them into undead defenders, winning a grisly victory. Not yet content, she then massacred a surrendering army to swell her zombie horde. Cir's religious order turned against her. In a mighty battle, she was slain by her former knightly peers. With her dying breath, she vowed revenge from beyond the grave—a promise she fulfilled when she rose from the dead as a dread knight. Feared by the people she once ruled, she now haunts the wilderness, biding her time until she sweeps away the living and rules a nation of the obedient dead.
• Queen Mab ( Archfey ; Monstrous Menagerie). Queen Mab is an archfey who rules an unseelie court. She exerts power over the realms of sleep, darkness, and dreams. Some shadow elves owe her allegiance, and she is a patron of some warlocks.
• Rhiz’Quethar the Consumed (Unique celestial; Monstrous Menagerie II). Just as a tree that topples to the forest floor becomes a meal for decomposers, a god that dies becomes a feast. When death claimed Rhiz’Quethar, the primordial god of the wilds became one with the decay that consumed its body, rising anew as a hive for fungus and other detritivores.
• Sleepless (Unique fey; Monstrous Menagerie II). Galloping between the planes, the Sleepless resembles an amethyst-colored, semi-opaque stag with a sprawling weave of antlers webbed with scintillating colors. Born of the fey world of the Dreaming, the Sleepless is an exceedingly dangerous predator that feeds on dreams. Though the Sleepless is intelligent, it perceives the real world as a dream. As such, it behaves in animalistic, instinctive ways and lacks a clear morality, making it an especially dangerous beast. Some scholars even theorize that the reason many creatures from the Dreaming only sleep for four hours a night is because those who slept for longer were devoured by the Sleepless.
• Zev (Unknown; Planestrider's Jourmal). Commonly found in the Astral Seas are the Zevites–a people trapped between worlds. These tall, lanky folk were originally brought to the plane by an ancient prophet called Zev, although some legends treat him as a tyrant-king. The Zevites have a timeless link to the Astral Seas, and frequently manifest psionic potential.

Fiends

• Axia (Unique devil; Monstrous Menagerie II). The leader of the celestial rebellion that created devilkind, Axia was originally the archangel who oversaw the laws of creation. Cast out for her uncompromising stance that rules should create a fixed social order, rather than promote justice, Axia now serves as the final arbiter of Nülda’s byzantine code of law. Although she looks no different from one of her advocate devils, Axia is the embodiment of judicial supremacy. She commands untold legions of tempters and bargainers, who trade power for corruption across the worlds of mortals, as well as the infernal judiciary, with its interrogators, judges, and wardens. Ever the strategist, Axia enjoys catching both her foes and mortal souls in legal traps.
• Belagon the Behemoth ( Fiendish Fire Giant Champion ; Planestrider's Journal). Powerbroker in Nülda.
• Belethias ( Pit Fiend General ; Monstrous Menagerie). Belethias is the general of the elite First Legion of Hell. In every infernal war, Belethias leads the charge against demonic hordes and angelic hosts alike. Despite having the power to do so, Belethias never seeks to displace one of the existing rulers of Hell. It has its eye on a greater prize: the annexation of the Material Plane as a new circle of Hell, with Belethias as its ruler.
• Birrezel ( Chain Devil ; Planestrider's Journal). A feared chain devil torturer and advisor to Mezarithir.
• Dominus (Unique devil; Monstrous Menagerie II). Dominus is unique among fiends, and one of the oldest. A former fey lord who embraced the infernal realm as part of his ascension to power, he exudes sinister charisma and revels in cruel decadence. The former ruler of a vast empire that spanned countless mortal realms, Dominus is the architect of Angolim. He maintains mighty infernal legions and acts as the ruler of a powerful assemblage called the Gleaming Court. Many suspect Dominus plots to use both these forces to retake his lost throne. Though deposed and exiled, Dominus remains a dangerous strategist and demagogue. He plays the long game, operating vast networks of spies and expendable assets as he prepares for his triumphant return to power.
• Ellmemog (Unknown; Planestrider's Journal). Nülda is ruled by Ellmemog, a powerful fiend with infernal legions under their command believed to be one of the most powerful entities in the entire multiverse. Nobody really knows Ellmemog’s origins. Were they a fallen angel which rose to godhood? A powerful fiend who ascended to deity? One of the creators of the multiverse, or a manifestation of the evil that pervades it? Does evil cause Ellmemog or does Ellmemog cause evil? Regardless of the truth Ellmemog exists, and there is no greater locus of malevolence and hate than that of the Betrayer. Ellmemog almost certainly isn’t their true name, and the personification of evil is known by many other titles—the Beast, the Adversary, the Queen of Lies, the Prince of Darkness, Mother of Perdition, the Lord of Spite, and so many more. Descriptions of Ellmemog also vary, from enormous horned beast-like fiends and sly serpents to charming, manipulative men or women. Most likely, the ruler of Nülda can take any form they wish.
• Galvakon the Iron Fire ( Balor ; Planestrider's Journal). A balor who runs the gladiator pits in Angolim.
• Izzig the Wastrel ( Nalfeshnee ; Planestrider's Journal). A nalfeshnee noble in Angolim.
• Mezarithir of Old ( Marilith Exemplar ; Planestrider's Journal). Ruler of Angolim.
• Rytlanyi ( Ice Devil ; Planestrider's Journal). Quartermaster for Nülda’s soldiers.
• Suro ( Erinyes ; Planestrider's Jourmal). An erinyes responsible for the Nülda army’s scouts.
• Vindica (Unique devil; Monstrous Menagerie II). Vindica began her existence as an archangel of military strategy and leadership. Cast out for her ruthless tactics, she quickly organized Yorgül-Thûn’s armies into a disciplined and pitiless fighting force. Vindica sees herself as a dispenser of justice and stubbornly denies she is no longer an archangel. She still wears Rise, an intelligent and yet-uncorrupted holy blade that no longer permits Vindica to wield it. Both Vindica and the sword believe the other will come around to their point of view, eventually.

Dragons

• Anthemyst (Great Wyrm Amethyst Dragon; Monstrous Menagerie II). In a glittering cavern miles beneath a major city, Anthemyst holds court, throwing galas, arranging diplomatic meetings, and otherwise inserting itself into the affairs of humans and other small folk. Although it has a tidy and well-curated treasure hoard, Anthemyst believes its friends are its real treasure (regardless of whether that friendship is natural or magically compelled). The motive behind Anthemyst’s meddling is obscure, but it seems poised to upset the current order.
• Beriax the Bronze (Great Wyrm Bronze Dragon; Monstrous Menagerie II). Beriax the Bronze sits sentinel on a rocky island, guarding a mystical artifact of world-shaking power. Beriax warns away any who approach the island and attacks any who ignore its threats, no matter their reason. For Beriax, the risk of killing innocent travelers is outweighed by the necessity of protecting the world from the dangers posed by the artifact.
• Blightbane ( Great Wyrm Black Dragon ; Monstrous Menagerie). Blightbane’s lair is in a lake within a wide swamp. If you offer tribute, Blightbane’s attendant hags will escort you into the black great wyrm’s presence so that you may ask it a question about ages past. If your gift is deemed sufficient, Blightbane will answer your question. If not, or if Blightbane doesn’t know the answer, the dragon will devour you for your impudence.
• Dragonpeak (Great Wyrm Earth Dragon; Monstrous Menagerie II). While most believe that Dragonpeak Mountain is nothing more than a peculiar rock formation, the locals that live upon its slopes know the truth: atop the mountain’s summit slumbers an ancient earth dragon. The great wyrm’s dreams are responsible for the mountain’s fertile farmlands, hardy livestock, and idyllic weather. Should the people of the mountain ever be threatened, the dragon will awaken—and in its rage, its response will be far from proportionate.
• Elathris ( Great Wyrm Gold Dragon ; Monstrous Menagerie). The great gold wyrm Elathris is buried beneath a ruined keep. Legend has it that long ago, Elathris gave its life to defeat the earthly incarnation of an evil dragon god. Some believe that Elathris merely sleeps and will rise again one day to battle evil reborn.
• Ereberus (Great Wyrm Shadow Dragon; Monstrous Menagerie II). Ereburus, the self-styled King of Shadow, haunts the penumbral forests beyond the Bleak Gate. From its lair in a labyrinthine bower of bent black trees, it sends forth its servants, such as shadows and wraiths, to snuff out the few points of light that prevent creatures of the Bleak Gate from spilling out into the wider world.
• Fallstaff the Jolly (Great Wyrm Copper Dragon; Monstrous Menagerie II). Falstaff the Jolly is the mightiest of the copper dragons and perhaps the most wicked. Feared and avoided by most of its kin, Falstaff spends its time disguised as a human jester, playing cruel and often deadly pranks. An accomplished spellcaster, Falstaff loves casting suggestion to lead people into peril, polymorph to cause people to unknowingly attack their loved ones, and hideous laughter to punish unappreciative audiences. Despite its love of practical jokes, Falstaff doesn’t like to be the butt of a joke. When mocked, it assumes its dragon form and wreaks bloody revenge.
• Frostflame ( Great Wyrm White Dragon ; Monstrous Menagerie). When the great wyrm Frostflame awakens, winter storms and glaciers march across the world. Heroes from many lands must join forces to turn aside its power. One day, perhaps, the strength of heroes will not be enough, and winter’s stillness will envelop the world.
• Krozorensith (Fiendish Great Wyrm Red Dragon; Planestrider's Journal). Powerbroker in Nülda.
• Lilgirm (Great Wyrm Fey Dragon; Monstrous Menagerie II). Lilgirm maintains a lair in the middle of a charming but deserted town in the Dreaming. Each of the settlement’s buildings, when not singing happy songs, whispers reports intended for Lilgirm’s ears.
• Lurissar the Moonclaw (Great Wyrm Silver Dragon; Monstrous Menagerie II), Lurissar the Moonclaw dwells in the Dreaming in a perennially moonlit desert of glowing silver sand. Its subjects—faeries of all types, as well as intelligent desert animals such as jackals and flying snakes—jockey for its favor, composing songs in its honor, bringing it scraps of news, and scurrying through portals to the material world to fetch silver treasures for the dragon’s hoard. Lurissar treats travelers as it treats its own subjects, punishing them for insolence or rewarding them with blessings and treasure in exchange for flattery. Particularly favored visitors are commanded to stay indefinitely.
• Marithidran (Great Wyrm Sapphire Dragon; Monstrous Menagerie II). Marithidran gave up its eyes in exchange for its prophetic gifts, but as its adversaries soon learn, it can see just as well with its empty eye sockets—better, because its view of the future is clearer. Marithidran’s self-appointed mission is to protect the “proper” sequence of future events, which coincidentally are those that preserve Marithidran’s power for many centuries to come. Marithidran interferes in the lives of the powerful, destroying promising inventors, punishing history- altering heroes, and eradicating anyone who dabbles in the forbidden secrets of chronomancy or time travel.
• Golden River, the (Great Wyrm River Dragon; Monstrous Menagerie II). The Golden River is the name of both a mighty river and the dragon that inhabits it. No bridge spans this river and nowhere can it be forded; boats ply the river only by the dragon’s good graces. When the Golden River is placated with offerings of treasure, its waters run smoothly and safely. On the other hand, riverboat captains who fail to throw the proper tribute overboard—or who dive to pluck even a single copper from the river bed—find uncharted waterfalls and maelstroms in their path.
• Iainith ( Great Wyrm Blue Dragon ; Monstrous Menagerie). The great wyrm Iainith, not satisfied with the tribute it received from a rich city-state, claimed the city for itself. Now the city’s ruins lie at the center of a vast desert. Satisfied, Iainith sleeps curled around a palace tower; when it wakes, its hunger will encompass new lands.
• Mohsilith the Diamond Willed (Unique dragon; Monstrous Menagerie II). The reason gem dragons hide away has a name. Gem dragons live in fear of the inexorable word of their self-proclaimed king, Mohsilith, Wyrm of the Pure Thought, the Diamond Willed. An ancient wyrm whose scales refract light like faceted diamond, Mohsilith’s immense psionic presence overwhelms the weak-willed into blind subservience. Mohsilith claims dominion over the world and all of its inhabitants. It is perhaps only by luck that the great draconian monarch considers himself a fair and benevolent ruler of his “subjects” and allows them to draw breath in his domain, blissfully ignorant of his existence.
• Redroar ( Great Wyrm Red Dragon ; Monstrous Menagerie). One hundred years ago, no lands were safe from the all-consuming fires of the great wyrm Redroar—until a clever gambler won a decade of the dragon’s mercy in a game of chess. Every ten years, the best game players in the world now travel to the dragon’s lair to challenge it in chess matches. If even one of these champions bests Redroar, the dragon promises to spare the world from immolation for the next ten years. 
• Skyshaker (Great Wyrm Purple Dragon; Monstrous Menagerie II). The purple great wyrm Skyshaker, the monarch of the great ocean, was once the closest companion of the storm god.Together they rocked the very foundations of the world. Since their great quarrel, Skyshaker hunts down any cleric of the god that dares to intrude on its ocean.
• Verdigrax ( Great Wyrm Green Dragon ; Monstrous Menagerie). The great wyrm Verdigrax once ruled an empire. In a poisoned land, sickly slaves constructed a huge tower of skulls to house the dragon and its treasure. Verdigrax’s current whereabouts are unknown, but the tower endures at the center of a noxious jungle, beckoning treasure seekers to plunder it.
• Velias (Great Wyrm Brass Dragon; Monstrous Menagerie II). The renowned high elf sage Velias, head librarian of the Brass Stacks, is happy to track down any obscure piece of lore for you—provided you honestly answer all their questions about why you need the information in the first place. In the rare instance the knowledge you seek isn’t in the Stacks, Velias adopts its true form, a brass great wyrm, and takes wing, traveling to other places of knowledge to find your answers.
• Vituperus (Great Wyrm Emerald Dragon; Monstrous Menagerie II). Centuries ago, Vituperus the emerald dragon was robbed by adventurers. Although the robbers are most likely long dead, Vituperus hunts incessantly throughout the tunnels of Underland, killing any prospective robbers it finds—a class that includes any intelligent creature it can catch. Vituperus has sworn to gather no new treasure until it finds its original hoard.

Far Realms Entities

• All-Mother (Planestrider's Journal). While her eggs are embedded across existence in places of fecund nature—dark woodlands, stinking swamps, lightless seas—the All-Mother never leaves her nest where she is attended by her cacophonous brood. When the stars are right her children hatch to spread her essence, seeking planar pathways to bring the worthy back to her embrace.
• Elder Chaos (Planestrider's Journal). This is the ur manifestation of things falling apart, of existence itself being senseless, directionless, meaningless. It lies in the center of the Far Realm in a vast cavern that no one seeking can ever find, surrounded by wailing cultists whose despair has subconsciously drawn them across the stars to bend prostrate before that which might destroy everything and spare them from their woe.
• Myriad One (Planestrider's Journal). With their ten thousand faces buoyed across reality by the essential idea of masks, deception, and form over substance, the Myriad One is said to reign in many fallen empires across the multiverse. Foremost among these is a city bound by endless black dunes that bleed into the deserts of other realms. Where the Myriad One passes, hollow grandeur and desolate wealth arise until nothing of true value remains.
• Opening Gate (Planestrider's Journal). Thrumming fearful tendrils bind together this coiling mass of living, glowing orbs, each a portal to a potential realm. The Opening Gate represents the desire to go thrash against borders, to search without purpose, as well as to lock away and hide without need. Those desperate to flee can offer themselves to this entity, finding safety but leaving behind a rift through which the Far Realm can reach out.
• Squamous Maw (Planestrider's Journal). This being waits in still waters, scaled, toothy, and ever poised to snap and devour, yet for some frightful reason it defers the deliverance of death. In it lies all the gut-deep fear that mammals feel when looking at the eyes of cold-blooded predators as they realize that they exist in this realm to be prey.
• Stealer of Stars (Planestrider's Journal). An immense moon floats above the Far Realm watching with six continental eyes, its thoughtflesh tendrils reaching thousands of miles outward through a web of portals in the dark night sky that link it to the uncountable realms it has corrupted. Yet the Stealer of Stars is more, comprised too of the gidim thoughtforms that call this plane home.
