Trajan is an Admiral in the Imperial Navy and commands the Fire of Heaven, which is the flagship of the task force he leads in Battlefleet Armageddon. While he was out patrolling, Trajan began receiving transmissions of Ork raider attacks from over two dozen Imperial planets, which he believed were part of a massive Ork incursion. Acting quickly the Admiral composed a message to Armageddon's Military Intelligence, that detailed the attacks and the worlds that had already fallen to the Orks. He also wrote, before sending the message, that he was taking his task force to intercept the Orks on what he believed would the next System they would attack. Unfortunately, these Ork attacks signaled the beginning of the Third War for Armageddon and the Imperium has not received any further messages from Admiral Trajan or his task force.
