Tricked?

Grey stared at all three of them, they were the only ones who might still be able to put up a fight. The other three at the Late stages of the Sage Plane were still lying on the ground, even if they could move, it was impossible for them to leave with Grey around unless Grey wanted them to leave.

Unfortunately, there was no way he would allow that, the fact that they had been capturing people and killing them for such evil practices made him hate them. One of the reasons he hated necromancers was not only the fact that they marked and tried to kill him, but it was because they would kill people and use them as puppets. It was a disgusting act that he felt should never be practiced.
