Lofty Mountains

Legends from all over the realm speak of remote passes, cataclysmic conflicts and relics of fell power within the ancient ruins of temples to defeated evils, the graves of terrible warlords, and sites of unspeakable rituals. Adventurers journeying through this region have few social encounters, a moderate amount of combat encounters, and many constructed terrain, natural terrain, and supernatural exploration challenges.

Tiers. Idyllic mountain ranges might be tier 1, while cliffs and crags ruled over by an ancient dragon would be tier 4.

Terrains. Arctic, hills, jungle, mountains, ruins, settlement, subterranean, temple, tomb.

Weather. 1–8 clear, 9–12 overcast, 13–16 mist, 17–18 rain, 19–25 snow.

Climbable. The terrain offers numerous footholds and pitted surfaces. Adventurers gain an expertise die on checks made to climb.

High Altitude. Breathing air gets harder at altitudes of 10,000 feet or higher above sea level, and adventurers not used to the reduced oxygen tire easily. Every hour spent traveling at high altitude counts as 2 hours of travel for the purposes of travel pace. For example, after 4 hours of travel a creature makes forced march checks every half hour.

After spending 30 days or longer at high altitude an adventurer becomes acclimated to it and can travel normally. Altitudes above 20,000 feet can only be acclimated to by creatures native to the environment.

Mountsbane. Travel time is doubled for mounts and pack animals.
