Shadun

The path of two friends, Relda and Amy, is forever separated: Relda is destined to kill the demon king Kloud, and Amy is prophesied to be his dark queen and bring Shadun, eternal darkness to the world.

A group of swordmen are tasked to bring the two back to Veas Sha, a magical realm that demons can't touch. To train or use them, perhaps, or to prevent Kloud from getting his hands on them.

But the road from Six Towers to Veas Sha is a very long road. Anything could happen on the way.

Even Shadun.
