SolarDust | ElvenSquad. Half-Demon elves were creatures born after the pranks of demons and succubus in the elven kingdom. Having imposed a powerful spell on themselves, the demons became elves for a while, and in this form they seduced elves for a long time, hoping to create a new race. They got a new powerful race, but the half-elves-half-demons wanted to stay in the elven kingdom and serve the queen. And the demons were de-spelled, had their… tails cut off, and were sent away from the kingdom.
