Clan Keldau was an ancient Mandalorian clan that existed during the time of the Mandalorian Crusades. Clan Keldau earned great renown in Mandalorian culture for the many combat trainers that emerged from its ranks, and bore the iconic symbol of a mythosaur skull as its identifying clan sigil. As time passed, Clan Keldau eventually died out, but the famed Mandalorian clan was remembered long after its demise; Tor Vizsla, founder and leader of the radical Death Watch, noted Clan Keldau's place in Mandalorian history in his manifesto, Ba'jurne Kyr'tsad Mando'ad.
