Crystallius used to be a man named Eric Xister. He died of frostbite in 1902, with nobody to help him. Now, he helps people feel warm, giving invisible hugs and putting blankets on people. He can talk, but he turns invisible whenever he does. He can go invisible at will, but not at will when he talks, he can teleport, walk through walls, move/float objects, and touch humans, but humans can’t touch him.
