The Peace Keepers homeworld and realms are quite possibly the harshest worlds to live in. The homeworld itself is a desert with rocky terrain and cliff walls. Tar pits fill the land as well. The only sort of water the Peace Keepers get here are bubbling underground hot springs, which they use to collect condensation.
Various stone structures are built up from the cracked ground, though most of them are simply archways and lookout towers. The Peace Keepers make a notion to not live in their homeworld, and instead live their militaristic lives in the seclusion of their realms.
