Wullf Yularen/Legends

Colonel Wullf Yularen was the Imperial Security Bureau officer assigned to brief Grand Moff Tarkin on board the first Death Star. Yularen used his influence inside the ISB to stay and watch Tarkin for the Empire. Yularen believed that eventually Tarkin would become disloyal and try to grab power for himself, and when he did Yularen intended to stop him, thus engratiating himself to the Emperor, who would appoint him to head the ISB. Wullf Yularen was killed on the Death Star when it exploded during the Battle of Yavin. To commemorate his bravery in staying on board, The Emperor created an ISB training center on the planet Mindavar, named it the Yularen Academy in his honor.
