Many of the Undead created on the world immediately fell back to death. A few others of various make, some of them spirits tied to the dead corpse to animate it, others made not quite with magic, yet not quite technology, but perhaps something else entirely, were not felled by the loss of Magic. However, with those created by tying a spirit to a dead body, what DID give way was the control the Necromancer had upon their minion. Sometimes, this isn't bad when the Necromancer didn't oppress them in the first place. Other times...Not so much.
Dread was not affected by the loss of Magic, himself. While he was animated with Magic, he was still a non-Sage Dragon, though lacking a spirit of his own. The Dark Magic twisted the bond, the spiritual link that his kind normally performed with others. While corrupted, the bond still went through...And his mistress' Spirit was then shared with him.While she didn't know how it worked, or that it even occurred, he was kept Animate by the spirit of his mistress, even without the influence of Magic.
Of course, despite all this...Without Magic, the balance of power upon the Barren Planet was temporarily broken. Those formerly the strongest were now weak as everyone else. Some still had power, those who bound the spirits of the dead of their own will to this plane, but the rest lost whatever power and protection they once had. Lauren was held in high esteem upon this planet...but not everyone had a pure enough heart to let that get in their way. And this girl, with the wings? Well, whoever she had ties to, they surely weren't gonna know who took her, not in this madness. Some would've wanted her as materials for a new Undead, others for even more unsavory reasons...It mattered not, there were those who advanced upon the group. Lauren and Jenny backed towards the girl, and Dread crawled forward in front of his mistress, her friend, and his own newmade friend protectively. He could sense the malice these people had. And while he couldn't feel most of his own powers, he could still fight to protect them.
