The two evil swords might be allies who like to betray each other a lot. :D

If you drain someone's soul I assume it still spawns good as new when they come back to life in the multiverse setting. Therefore, soul draining is more like just another way of killing them rather than permanent doom. otherwise I wouldn't have this canon.

Due to me posting on breaks at work I might disappear without continuing an ongoing conversation until a few hours later at least, for future reference.
