This is a Templar Knight. Descendant from a long line of nobility and the youngest of four, being the youngest he was entitled to none of the families riches. So being that he had nothing to look forward to at his own house, he set out on the Crusade to become rich, and earn a place in Heaven. Already being trained as a knight, he was accepted and at once was sent out to the Holy Lands of Notch.
(I put together the skin from looking at multiple sources and getting the general idea of what a Templar knight would look like, and no, Templars are not from assassins creed, look them up.)
