Character : Knightmare
Knightmare was, once, a true unicorn. Like others of his ancient and immortal kind he was a peaceful creature and a steward of mystical and sacred places. Until the Demon Queen Shine began her attack on his world. Along with dragons, she mutated and warped beings from other magical races - unicorns included - to her own ends, destroying everything that they were and creating cruel, twisted, warlike minions from the remains.
Knightmare is Blackjack's evil-tempered steed. This suits him perfectly as he loves the thrill of the hunt and running down their enemies.
