Ling aimlessly allowed the fire to wander between his fingers as he spoke "Yes I am aware of our origins, though to be honest my father didn't like the subject much. But, considering the circumstances I suppose I can share with you what he did divulge"
With a snap of his fingers he extinguished the flame, as well as the fires burning around "We, the demons of Xi'an, were once just a humble tribe in hell. The clan of fire demons specifically. When the great schism began we sided with the Totudage, as did the other elemental demons. But we demons of nature always saw ourselves as different from other demons, so we never really integrated. After the war was resolved, and the enemy deposed, the alliance of continence began to falter. Old rivalries came back to the surface and threatened to boil over. This was when the elemental demons, such as me, fractured off and returned home."
Ling paused to see if his guest was following before continuing "Years after returning to our homelands the humans of Xi'an, having found an ancient spell to summon demons, begged the protection of the elemental demons from invaders. Unfortunately, the spell was so old that it dated back to when we had all been a single tribe, before we split up by element. We fire demons felt we were bound to follow the request, while others felt it was void. To shorten a long story we fought a civil war and our leader won and took the throne of all the four tribes, and then we came to Xi'an to fulfil our oath. This is also why fire demons are the government of Xi'an, as emperor I am the leader of all four clans."
