The crystallization of a foolish and wicked man’s tragedy.    Lore: There is a tale, a legend of a man who tricked the devil to not take his soul to hell, but this man was too wicked to enter heaven,     Thus he remains trapped in this world, wandering endlessly across the lands.

  At times, cold, confident, and haughty, but there seems to be a hint of both crazed mania and deep paranoia in his countenance as he searches every shadow in the room closely.     At times, he can fly into fits of rage and violence and hurt himself and others around him.    Truly, this man is one to be pitied. 

When summoned he appears as a thin-wispy-looking blue-haired man with a sneering face, wearing a scholar’s toga, under which is a sleeveless button-up vest over a dark blue tie and a light blue polo shirt, with black pants, black shoes, and black gloves to match.     In later ascensions, his appearance becomes more disheveled and his clothes become more torn and bloody.

It would be best not to let the two meet.

He approaches the saints daily and asks them to pray for him.     It does little to sate his fears.
