The moment that Opal appeared, she activated her Illusionary Domain, and then placed the whole thing inside a [Pet Space] pocket dimension.
The warriors felt themselves being shifted, but as the Illusion matched perfectly to the Library, they couldn't tell what had changed in time to try to stop Opal. So, while they realized that something had changed around them, none of them realized that they were no longer in the Library at all, and were actually in a separate space completely controlled by Opal.
Ghostly voices howled from the shelves, and pinpricks of red light appeared in the shadows as the lights in the room began to dim.
"Shit. Necromancer," one of the warriors cursed, as he moved to protect the rear flanks of his group from ambush.
None of them could spot the Necromancer. They could sense the Lycan, the old man and the snake. But everyone else was hidden from their senses.
But there had to be someone else here.
