The Stack is a jungle-like biome composed of spaced layers of Cirrus clouds. The large number of holes and places to fall makes it dangerous for most humans to explore. The residents of Ouranopolis only rarely require objects from this place. Rumor has it that ruins of an ancient society lay deep within, overgrown and lost to time.
Creatures of the Stack include:
Armstrider: dangerous orangutan-like humanoids
Ambush Lizard: A predator with a natural magic camouflage.
Leaping Glire: A small mammal that can jump large distances
