BoneClan

Origin
BoneClan originated when an evil, twisted cat named Squirrelstar, became leader of PoolClan. He was cruel and wanted to rule all the clans for himself. When he became leader he forced all the queens in the clan to have kits so that BoneClan would grow.

Loyalties
Squirrelstar acted as a loyal warrior the moment he was given the title, he continued to train without his mentor to be the best warrior in the clan. He proved his loyalty to Poolstar when she had to give her kits away without the clan knowing she had had them, or been mated to Stormstar. When Squirrelstar confronted her on the border she made him swear that he would never say a word and so he didn't, and kept it a secret. Poolstar saw him as an obvious deputy when Beetlenose gave up the title and Squirrelstar proved her right. Until he became leader, Squirrelstar was an admirable cat.

Ambitions
When Squirrelstar was a young kit, he had been told of the story of BloodClan. Instead of recoiling and silently vowing his loyalty like all other kits did, he listened intently, admiring how Leopardstar and Tigerstar had been so determined to create a "pure" clan. Suddenly he was having dreams of uniting the clans with his own future mate and he when he was apprenticed, he started to gain the attention of Foxtail and they became strong mates. During his warrior moons, he realised that his dream was suddenly becoming a reality and this drove him to train hard so that he would become leader.
