Raglov had finished speaking and opened a teleportation portal, the coordinates provided by Lord Malin. It led through a shallow channel constructed in the Subspace by the World Tree, a very safe area that would not be intercepted by Chaos.
Upon entering the new battlefield, Raglov had already seen Ails. He had switched bodies, a very standard idea for a Lich.
Raglov checked the souls he had harvested and found that the Lich had indeed not broken his oath; he had only harvested those Chaos souls that had not yet dissipated, including those of both Chaotic Believers and members of the Chaos warbands.
Chaotic Believers are not considered human, so if Lord Ails wanted to harvest their souls, Raglov wouldn't care—and neither would anyone else.
In the end, this Lich had harvested some six hundred Soul Coins, a yield with which he seemed quite satisfied.
