Xeren is a demon, formerly a deity. He created Euclid in the distant past and was the king of the gods until his half-demon son Kaz stole his soul, turning him into the Demon King. Xeren has four children: his daughters Blood Queen and Savannah, the heir to his dark throne.
He killed the mother of Harrison and Piercy Provost, while under the control of Kaz. Shortly after Mrs. Provost was murdered, and Mr. Provost went missing, Xeren recruited the two Provost brothers. The two of them joined the Demon, as they felt that being in allegiance with the Demon would help them to accomplish their goals, and get over the loss of their parents. Neither of them realized that the Demon was actually Xeren, the same person that murdered their mother. Sometime after the Provost brothers defected from the Demon, they learned that their father was still alive, and that the Demon was the one that murdered their mother.
Xeren has red skin, solid yellow eyes, and a pair of twisted horns atop his head. He also wears powerful silver/black armor that is hot to the touch as well as a long red cape.
Xeren is an incredibly intelligent, ruthless sociopath. He has no mercy for anyone, willing to crush his enemies regardless of how much he loses as long as he thinks he will come out on top. Xeren also orders harsh punishments for those under him who question his orders, going as far as to require unquestioning loyalty from his subjects before they join his ranks and killing them if they disobey.
His "weak point" is his family. While Xeren makes every effort to make sure his children obey him as much as his servants, he is more than willing to let them question him on his choices. Xeren cares little about what they do so long as it furthers his plans or does not get in his way. Even if his children were to defect from his side, Xeren would only order their capture and have them kept as prisoners unless they agree to become his loyal subjects and only allowed their previous freedom after serving as a spy.
Xeren is capable of flight, spontaneous generation of fire, clairvoyance and teleportation. His scream causes those who hear it to panic. Xeren is a skilled hypnotist, but requires the proper equipment and time to work.
