Legends and Lore

With an Arcana or History check, characters can learn the following:

DC 10 Titans are semi-divine creatures from the dawn of time.

DC 15 The literal children of gods, empyrean titans are mighty warriors and powerful spellcasters. Their wounds heal with supernatural speed.

DC 20 Eons ago, King Fomor and his many degenerate children were banished to the Dreaming. Each fomorian has a bulging eye that is both the source of their magic and their greatest vulnerability.


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.


Material Plane Empyrean Behavior

1 Sitting on a throne, staring at beautifully gilded prison walls, longing for distraction

2 In a rage, hammering futilely on an indestructible stone door

3 Summoning and dismissing illusions of worshipful mortals, magnificent architecture, and forgiving parents

4 Escaped from its prison and on its way to reclaim its power 

Planar Traveler Empyrean Behavior

1 Dictating a message to a ball of light, which then races off; several more balls of light wait patiently to receive messages

2 Looking for battle with opponents of equal power

3 On a holy quest

4 Holding a feast, festival, or dance for locals


Some empyreans maintain a semblance of rulership within dungeon prisons, while others wander in exile far from the Material Plane. Fomorians and their ilk inhabit underground palaces in the Dreaming.
