Blackthorn

Blackthorn is a massive bulky tom with short black fur and blue-purple eyes.

Blackthorn accused Hazelstorm of killing Flurryfoot, when in fact it was Blackthorn who killed Flurryfoot.

History
He stalked his mother who was hunting outside her barn, and leapt onto her. She bit his neck twice and left a nasty wound on his flank, but he managed to kill Hazelstorm.

He eventually died and woke up in the Place of No Stars.
