SkyClan was the fifth Clan, but was forced to leave the forest because Twolegs had invaded and taken over their territory, turning it into the Twolegplace cats see now. Their current leader at that time, Cloudstar, appealed to the other Clan leaders at a Gathering and asked for them each to give up some of their territory for SkyClan. However, each Clan gave reasons to refuse to let SkyClan stay, and in the end, the Clan was driven out. Because of this, Cloudstar swore that SkyClan would never look to their warrior ancestors again. Cloudstar's mate, Birdflight, was offered a place in ThunderClan by Kestrelwing, the ThunderClan medicine cat with her kits, since she had just given birth to them and they were too young to make the journey to SkyClan's new home. With much sorrow, Birdflight accepted and promised Cloudstar that they would someday meet again.

The modern SkyClan is a Clan of cats with strongly built hind legs which allow them to jump great heights or distances inherited from their ancestors, ancient SkyClan. They have rough, hard gray pads which help them to jump and walk long distances on hard, rough surfaces without breaking skin, which makes them infected. This feature allows them to climb and hunt in the trees, hence the name SkyClan. They are very powerful cats, who are a bit like ThunderClan, eating mainly squirrels, mice, and many kinds of birds.

SkyClan was founded by Skystar. He is a light gray tom with ice-blue eyes. The first medicine cat was Micah.
