Karth Valerius is a vicious and well respected gladiator of the coliseum. He wins almost every fight due to an internal rage that bids him to destroy anyone and anything in his path. He despises people, they deserve none of his trust or his admiration as he learned from his life. However, he also hates what he finds lying in his wake of destruction. In the middle of an intense battle Karth suddenly finds himself in Equestria. Karth's rage burns deep, and Equestria itself may be destroyed because of someone's mistake. One simple foolish mistake.
