The Shut-In Demon King Among the Stars

You can think of this as fanfiction for the game Stellaris, or as a fantasy tale set in space.

The stars stretch without end, and only war is eternal. The age-old war between the Celestial Realm and the demon race burns through the endless galaxy.

But what does that have to do with me? I'm just a shut-in Demon King hiding in a corner.

From witches to liches, from succubi to vampires, little do they know that the destinies binding them together are waiting just around the corner.
