Exermis

"The one who decides the fate of all, even gods themselves, is I, the harbinger of judgement."

- Exermis (Male) to Silvia Bortre

Background
Formally the youngest sibling of the demon king and high commander of the demon army. Exermis conquered and destroyed many universes until they saw no need for such things, but in response, their brother banished them to a plane between reality and fiction.

After banishment, Exermis saw that all universes are like stories, like a book waiting to be written and told, and so, they began creating an infinite number of these "stories" in their plane, some that even contradict the laws of physics and nature entirely, and others that span indefinitely to no end.

Eventually, they found a breach in the plane they were banished to and entered it, soon finding themselves in a "futuristic" world full of lights, and in that world, they met "The Author". "If you want to create your own world, then why not take over?", they said as they pointed to a desk with a stack of empty sheets of paper, and so they did...but they wonder, is the world they went to truly real, or another "story"?
