Optimus Caliph is a powerful elementalist guarding one of the sealed gates leading to the Door of Komalie. He is most likely the highest ranking Mursaat available in-game so far. During the Charr invasion of Kryta, it was Optimus Caliph who turned the tide of the battle and fought alongside Saul D'Alessio. Lazarus the Dire and Mercia the Smug also fought at his side.
