- MoonClan, founded on the belief that the Clan's founders themselves were gods and held a power much stronger than StarClan in their hands. They, as a Clan, follow customs that are completely foreign to the other Clans. A deputy that makes it leadership is believed to be the reincarnate of one of their ten founders. Their personality and the way they led let the Clan members themselves choose who they believe their leader to be.
- Their customs as a Clan aren't very different, however the freewill to believe in StarClan is forbidden, the punishment normally being banished or death depending on the severity of the belief and crime of the belief. The Clan follows the same code of conduct as the other Clans, to put on a false view that they believe in StarClan. However, it is the Clan, itself, is suspected and famed for having a great lack of belief in StarClan.
When it comes to deciding who leads their Clan, MoonClan has what they call the Crucible Trials where two or more cats challenge each other to a fight to the death. If a cat surrenders they are normally shunned or banished from the Clan altogether.
