Curious Nightingale: He is a man, who despite his youthful appearance has seen horrors of this world and the world beyond which have forever scarred and tormented him. Most of those scars remain unseen, and he is as cynical as he is guarded. His eyes are a fiery emerald green, and look almost jewel-like and inhuman, and a long cascade of hair black as shadow and richer than silk. He has lost everything in this world, and regained it all. He understands the only way he could survive was to beat the devil at his own game. He is calculating but not yet entirely cold, he is both suspicious and trusting, and is determined that no one will make a victim of him ever again.
