During this time, He is hunting Selene and her daughter Eve for their blood in order to become invincible and win the war.

At one point, He and his army follow Selene and David to the home of the Nordic Coven and proceeds to engage the entire coven in a battle (aided by his Vampire lover Alexia) but his prey ultimately escapes. He later leads an attack on the castle occupied by the Eastern Coven. During a fight with Selene a single drop of Marius' blood lands on her lip and it is revealed that he has already drained and presumably killed Selene's lover the Vampire/Lycan hybrid Michael Corvin in order to gain the temporary powers that a serum create with Michael's blood gave him. However, Marius loses as Selene gains the upper hand and rips off his spinal column. After his death, Marius' head is then removed from his body by David who shows it to Marius' Lycan, forcing them to fall back.
