How about Whiteheart? He was a loner named Snowy, but wandered off to explore the territory of StormClan. He stumbled upon the camp, and became fascinated with Clan life. He joined StormClan, and was given the apprentice name Whitepaw. His mentor was Sparrowheart, a clever senior warrior. His warrior name was Whiteheart, and he fell in love with a beautiful silver cat named Whispersong. Whiteheart died in a battle between StormClan and (insert Clan here) from a fatal blow to the head, which he hurt a few days ago. He always remained a loyal StormClan warrior, even in StarClan.

I hope you like it!
