Adracum was one of the many Jiralhanae that participated of The Battle of Earth. He with he's pack mate, Brutus(Halo: Sword) found the body of Rick-181 laying in the ground, near Socorro Cliffs. He asked to Adracum what has possibly left him in this state, with Adracum replies that probably were the 'scum' of the Sangheili. Then the two take his body and travel with him to Sublevel 09. When Rick wake up, he noticed that 000-Guarder wasn't there anymore, and has perceived that Guarder betrayed him. He noticed that Brutus and Adracum were fighting for a piece of junk that they found in the cliffs, and tried to get up, but Brutus killed Adracum, pushing him to his death in the pool that hides the Halo Array Device.
