Keriss - Soom Dia head on Soom Chrom Bane of Wood body - Birthday 17 march 2010
He is an undead demon, slave to Kael and sent to the dominion of Gilgamesh to assassinate his generals.
He was captured after he succesfully murdered several generals cause he was not able to kill Nazheradei, too powerful for him.
Nazheradei didn't killed him but decided to keep him as a slave, at first. Than, after several months, he fell in love with him. Maybe Keriss feels the same but it is not easy to know cause he talks not much and always with lower voice.
Keriss is currently a butler for Nazheradei and he is a friend of my dear Nabibi, the maid,  they were in the same castle in Gilgamesh Dominion ^^
Keriss has body blushing by Soom and face up by La Coterie de la Lune
