Aurums were a race that the founder of the 2nd Warlock Dynasty, the Taboo Lord discovered when colonizing other planes. Aurum blood essence possessed the mysterious power to purify a person's soul and upgrade their soul aptitude.
After nearly slaughtering all of the Aurum experts and extracting their blood essence, the Taboo Lord has significantly upgraded his soul aptitude. When he broke his curse of a low soul aptitude, he advanced by leaps and bounds on the Warlock path, and then finally founded the 2nd Warlock Dynasty and became one of the 10 strongest people of Jeddah Universe since the beginning of time.
Due to its miraculous effect, aurum blood essence has naturally attracted the greed of countless Warlocks. After a long period of time, the aurums were practically exterminated, while the aurum remnants left their original plane, scattered and hid in the various planes, and became existences that could only be found through good fortune.
