After learning that Vorus, the leader of the guardians, was misusing his power, Tyrum had him brought before him. He questioned him as to his aims and revealed his wish that Vorus would be removed from his post. Angered by this, Vorus declared that he would resist and civil war broke out between Tyrum's men and the guardians. When he saw that Nerva had been set on a collision course with Voga, Vorus and his ally Magrik tried to launch the rocket so Tyrum shot them both.
