Nekros

Nekros was the first sorcerer, who create magic. He created the great book of magic, which the goddess Discord  lifted from the bottom of the Dead Sea and presented it to the witch Haleh. When Haleh mastered magic, she wanted to call on the spirit of the great sorcerer to teach her real power. After the spirit appeared, then Haleh invited him to inhabit her body. After Nekros returned to life, Hercules  appeared in the cave and tried to send Nekros to the kingdom of the dead. At first, Hercules did not succeed, but with the help of the witch Seska, he was able to open a portal to the world of spirits. And when Nekros shot one of the fireballs at Hercules, Hercules fought him off with the help of a magic book and Nekros was thown into an air whirlpool. After that, he disappeared.
