Story continues on Webnovel under "Prince of Nightmares: Banished to Hell With a System"

As punishment for the crime of being born "wrong," Lokus is banished to a foreign world where power reigns supreme. A place where the worst of the worst are cast to after death, a land said to be one of eternal suffering and solitude. A land called the Aldark.

Hell.

With newfound power coursing through his veins, Lokus embarks on a relentless ascent, driven by the desire to seize control of a world that once pushed him aside.

But the path is treacherous, and he must begin at the bottom.

Aided by his Phantom Monarch System, and the mysterious Shadowfire Clan, Lokus would bring Talisma to its knees for its transgressions.

.....

Readers will learn about the world as Lokus does. However, if you have questions and I deem them okay to answer without spoiling anything, I'll be more than happy to reply. Otherwise, you'll have to wait for Lokus to learn about them.

The power system is inspired by both cultivation novels and rpgs, and the world itself by several fantasy books I loved growing up.

If you like gritty scenes, systems, no harems, and struggles between good and evil, this might be the story for you.
