Lancaster's speed at the moment was even faster than his speed was when he fought Atlas last night! It was even impossible to see him as he moved. He was like a ghost who appeared from one place to another in an instant with his sharp teeth around the neck of the Mages. He tore their necks off.
The mages who used spells in unison couldn't do anything if they couldn't even see Lancaster. Even Yovana didn't know how Lancaster suddenly became like that. She had some spells of Lilith that she could use to stop Lancaster, but that was only possible if she knew where he was.
It was impossible when Lancaster was right in the group of her dead.
One after another, the dead kept falling to the ground. They didn't scream in pain or cry. They just lifelessly dropped to the ground as their heads were taken off.
Everything happened so fast that before Yovana could control things, all the men she sent to stop Lancaster had been killed.
