Warhammer Heretic, Pureblooded Human Night Lord an

Coral accidentally traveled through Warhammer 40k and became a rebellious Chaos Space Marine at the beginning. He was still one of the Night Lords who defected to Chaos, but he accidentally gained the ability of void and dark matter.

But what a heresy this is! Why is this Astartes a pure-blooded human! Why does he have the power to control the void and dark matter!

Why did he regenerate after his death?

Chaos, Empire, Zerg, Eldar, Necrons, Orks, Tau... Wait, here comes the Void again?

Kolar is a void force from a higher dimensional universe.
