I just noticed, back on Page 10, that when Vestec creates the undead (at a rate of 1% of those who died), he also cursed 25% of those who died to have their souls sent to his Realm of Madness instead of Reathos' Wraith Stone.

I hadn't noticed that before. Probably a worthwhile point, especially for Farxus. I'm not sure what Vestec does with those souls, though.
