This is fanart from the game Armello, which is amazing. If you were a backer for Kickstarter and donated 45 bucks you got the Bandit Class characters, which are some of the best if you ask me.
Horus is a badger who once served the king before the King became corruption. He loves reading and reciting poetry and has a soft heart under his hardened exterior.
My headcanon for him is that he was in love with the king and couldn't stand to see what was happening to him so he left.
