The Caliph is the leader of the Warrior caste within the Assamite Clan. He is, in theory, the greatest combatant among the Children of Haqim, though few Caliphs have been masters of every form of combat. The Caliph's primary duties are to advise the Eldest on matters that pertain to the defense of the Children as a whole and to guide the warrior caste in its defense of the clan, its holdings and its mortal subjects. Additionally, should a trial by single combat arise whose outcome affects the entire clan, the Caliph is the Cainite who fights on the Children's behalf. No records of such an event exist, though the fact that this is the duty of the Caliph suggests that such circumstances arose at least once before.
