Starclan

Starclan isn't really a true clan, more of a warriorcat heaven. When warriors of a clan die, they go to Starclan. Starclan watches over the clan cats and they give medicine cats omens and prophecies. Starclan cats can visit cats in the real world through dreams, most commonly to give prophecies or warnings. The Dark Forest is the exact opposite of Starclan, the cat equivalent to hell. This clan is usable.

Territory
Starclan land has a variety of terrains to suit cats from different clans. In Starclan, there are no borders between clans. Here the land is always abundant with prey and the weather is always nice, no matter what terrain you are in.
