Asterius is intelligent and independent. He is slow to trust, suspicious from his life of being an outcast. Slower still to expose himself, hiding himself behind others' expectations and instead choosing to act as a stereotypical minotaur: ferocious and warlike.
In truth, he is a much more laidback being, preferring to read stories and search for interesting knowledge, using it as a form of escapism from his life.
He's uncomfortable in open spaces, preferring closed environments, and doesn't like not being able to feel the earth, finding much comfort in solid ground and the magic that rests there. The only reason he's good at sea is so he can reach land faster.
He enjoys creative ideas and will adapt without protest to new methods and spells though he prides himself on being able to use the magic he knows consistently, with little fluctuation.
He is intense, accepting, selfish, and extremely loyal. He will rarely put other people above himself, but he will readily put friends above all others.
