Shrouded in a hooded cloak that cast his features into shadow, Kaine cuts a silent and mysterious figure. He is of above average height and broad of shoulder, clothed in fine clothing of a muted color. A glance underneath the hood reveals a handsome face with a short, well groomed beard and furtive eyes that gleam with intelligence and a powerful force of will.

Kaine had appeared eager to leave Gateway, to the point of appearing almost paranoid, as if he was being pursued by someone wishing him harm. However ever since boarding the Sunset Mist he has become more relaxed, revealing a more sardonic nature.

Though he appears to be of a taciturn and introspective nature, when among boon companions and those he trusts Kaine opens up and can offer excellent advice to those who choose to listen.
