Marvellous Chester is "a man of mystery lost in the past". He is a merchant, and like the Chosen Undead, he was dragged into the past by Manus, to the realm of ancient Oolacile. Little else is known about him but his weapon of choice implies that he originates from Carim.
His armor is an "exquisitely sewn aristocratic suit [that] allows its wearer to move in silence, lending well to stealth". His gloves "have no distinguishing features, but are of extremely high quality". His trousers are "exquisitely sewn" and "decorated with silver trinkets of varying sizes, and have straps on the inner legs for carrying crossbow bolts".
