In the 90's, a gigantic black monolith appeared out of nowhere, his base glowing with a dark red aura. There, a crowd of demonic-looking creatures emerged, looking as confused as the humans in front of them. Nobody knows how nor why this monolith appeared on their world.

For a couple of decade, tension between humans and what they called demons escalated, leading to a imminent war. As a conquering species, demons attempted to invade Earth, but humans' more advanced technology prevented them to do so.

Nowadays, a fragile peace is established between the two species, but most of humans are suspicious, or feared about demons. For an unknown reason, only demons can passed through the monolith's portal, while there is no form of magic in their world.
