Ysla Caine was one of the Bone Card creatures used by Lucious Incendous, Champion of The Elemental Plane of Fire. She was bald, and had a long scar running down the left side of her face that crossed over and through her left eye, resulting in a milky eye. She wore expensive armor that didn't cover her arms, revealing a landscape of tattoos that seems to shift and move. The tattoos powered her magic; she was a master of the Mystic Arts, and would channel her magic through the tattoos. Killed by Skud Derringer and his team in his Bone Card Battle against Lucious Incendous, and resurrected after the battle was over.
Later, when Tiamat was attacking the Elite Forge to acquire the piece of The Orb, The Tower of Grey chose three of Incendous's crew to take with them back to The Tower of Gray. Ysla Cain was not one of them. She was killed when the blue head of Tiamat came down and bit her in half.
