Aeoryi

I had an idea for something in the king's folly universe that would take place after the main story.

Piercing the Darkness:

A hallowed city sits on an desert island with only broken ships and junk to live off of. 

Several monsters hunt within the junk, looking for people or supplies. But other dark things hunt nearby as well.

The Disquieted Ones also are the scourges of the wrecks, and  provide a source of both power and hazard. 

All magic, Otherside or trace turn into crystals here in significant. An odd place to live in, but after a Voidbringer named Carnage, and another named Desolation arrive, the city is under constant attack. It is up to Fenrin and Nymphis to save them.
