This is an extra chapter I thought I'd add, its what I know about the founders of the 5 clans:

Skystar:
Lets start off with the name, Skystar's name was Clear Sky (I know, not a clan cat name, but the clans didnt exist quite yet)
Clear Sky was a Tribe Cat that lived in the Mountains.
His mother was named Quiet Rain and his littermate a Tom named Gray Wing. He also has a little sister, Fluttering Bird, who sadly died at a young age and a little brother named Jagged Peak.
As said, he lived in the mountains with the tribe till prey became very scarce one Leaf-Bare and the tribe cats split in half, one half traveling down the mountains to find better hunting grounds which left the other half that stayed in the mountain a better chance of surviving. On this journey, Clear Sky lost his mate, Bright Stream, to a hawk.
They arrived at a forest, where Clear Sky made his camp and was the first to set up borders, his fellow travelers settled down on the moor and lived in Tall Shadows camp for the time being. He took on another mate, Storm, who had his kits. She sadly died as a Monster destroyed her den, Gray Wing however managed to save one kit whos name was Thunder.
After a few seasons he took on another Mate, Star Flower, and had healthy kits with her who lived.
