Ondaus

Ondaus is a post-apocalyptic underground world inhabited by furries. The surface is destroyed and only exists as legends for those who live below. Furry civilization has developed in the infinitely vast network of caverns and tunnels, and underground cities and factions have sprouted in large caverns. Bioluminescent mushrooms, magic, mines, and dim lamps are common sights in the depths of Ondaus. The underground world is still mostly unexplored, and unknowable horrors lurk in the deep. Beware.
