The demon god was Mortal, once lord of lightning, who had crossed into the plane of magic and finding himself in a cave after going through a portal, found Haruna's treasury, containing most of the magic in existence at the time, enough to rip apart reality for all the worlds. Drunk with power, Mortal stole most of the crystals, then went back through the portal and created a race, known as the demons, who would wage war on the other races and gods until Mortal conquered all. The demons have the appearance of humans, but for their pure red skin and other features. They have short, stubby goat's horns on their heads, accompanied by pure red scales across their whole bodies, long nails that are more like claws, fangs and a long, scaled tail. Their blood is also toxic, thereby any dog to go against demons will most certainly die if he bites.
