Aquillo Isbrand is the ice god master and one of just two god masters who was given a last name. He was one of the first god masters to be brought into existence, and although he is extremely powerful and possesses the most dense aura among his kind, he is by far the weakest physically. Despite his looks, he tries to avoid conflict at all costs, and will not reveal himself to any ice god tiers unless they have two or more comrades who they would trust their lives with. The scythe he wields is called a god sheathe and can create any phenomenon associated with cold weather. It also seals a large amount of his power and keeps him locked in the winter world where he has been for centuries.
