Meta Thanaton: Maledicti

I recommend reading the first two books to better understand what's going on in this one.

Book 1: https://my.w.tt/s3VdlOwHRR
Book 2: https://my.w.tt/7h0HCcCHRR

Only souls that have bonded with the greatest evil get cursed by the Gods of their multiverse.
They get sealed away in a place that's between, outside and inside everything. A place that shouldn't exist where all they can do is wait for the Curse to find them. Their souls will be disfigured to a point of no recognition and like this they will have to stay for the end of existence which everyone should know is eternal. But one dark spirit, the darkest of them all, is different... he will bring chaos, calamaty and destruction upon all realms of existence and there is no one that can stop him... Or is there?
