Necropolis Expansion

After Netherius intentionally allowed Alice and Claudia to escape from his grasp, he grabbed Isidor's unconscious body and cast a spell that teleported him back to his residence.

The Onyx Cartel had different mansions all over the western area of Novaria, and their residence at Limsa was located on the edge of the death's ichor that corrupted the city.

Since the death's ichor was a creation of the necromancer, it shared a piece of his consciousness, which allowed Netherius to see any area that had been corrupted by it. Moreover, he could also warp his body through the ichor and teleport himself.

When Saturio was defeated by Zac and Curtis, the necromancer considered warping himself to the area to protect his subordinate. However, he knew very well the type of warrior that Saturio was.
