Kamu is the God of War/Combat. Responsible for overseeing battlefields and occassionally providing support to the side he favors, Kamu most often presents himself to mortals in the form of a menacing warlord with his features obscured by a grand, horned helm and heavy armor - though there are tales that state that Kamu will remove his helm to those who prove themselves worthy.
In stories and plays, he's usually written as a vengeful, angry man with a lust for power and bloodshed that can only be tamed by his wife or son.
