Netherly Swathe
The Nether Realm was home to the Netherworld, a place where a single entity reigned supreme and stood above all else. This individual's name had long been lost to the passage of time; however, those who knew of their existence in this era called them the Netherworld Monarch.
The Netherworld Monarch was a unique existence. There was always a limit when it came to one's lifespan, whether it was True Dragons, Trephasias, or other long-lived races. It could be a thousand years, tens of thousands—even a million! Nevertheless, time would eventually catch up at some point, and one would ultimately be erased.
Death could not be avoided as it was the Will of the World—the fate of all that comes to exist.
There was one way to circumvent death, but that method required one to step into the Divine Realm—an impossible task for the vast majority.
