Seven Demon Elders

The Seven Demon Elders (七魔皇老) are the seven demons created from Anos' own blood 2,000 years ago, just before passing away. Their existence was created and given life by magic, not by reproduction. It was prepared because Anos needed a body to inherited his own blood when he reincarnated.

History
The Seven Demon Elders are the seven demons created from Anos's blood. They inherited the traits and talents of the Founder. Before Anos reincarnated he commanded these demons to have children and expand their bloodlines. These seven demons started the Demon King Academy Delsgade to raise the next generation of Demon Emperors. Their followers and subordinates started calling them Seven Demon Elders since Anos didn't give them names because he was too busy with his reincarnation.

During the the 2,000 years before Anos reincarnated, the Seven Demon Elders collaborated with the Hero Kanon to replace Anos as the Demon King of Tyranny in order to create a decoy for when the human race exacted their revenge. As part of their plan, they had their roots fused with Kanon's six other roots, leaving Melheis Boran out as Kanon's remaining root belonged to himself. They all agreed to have their memories wiped out since they couldn't lie to Anos if they ever met after he reincarnated.

Influence
As the direct subordinates of the Demon King of Tyranny, the Seven Demon Elders held considerable power in Dilhade. Their names commanded respect and honor, with many looking upon them, as their influence was second only to their creator and master, the Demon King of Tyranny.

Trivia
