There was once a group of many cats that lived in one forest, but it was hard for such a big group to survive. The ones that were disabled, sick, or old weren't noticed or taken care of so they died off quickly. One cat, Luna, was noticing the problem of this big clan , and thought it was better to split into smaller clans. She told the leader, Jaw, this idea but he wanted to remain in control. Luna continues to spread her idea and soon the clan breaks up into smaller clans. Jaw discovers what Luna has done and attacks her. A few another try to defend her but they all die. In the afterlife, Luna is made leader of the clan in the sky. It is later called Luna Clan. LunaClan is made sacred.
