Phlegethos was the name of the Fourth Circle of Hell and resembled a fiery plane where the wind carried the whines of the trillion lesser Devils. Active volcanoes, rivers of liquid fire, and ash hills covered the landmass, raising the temperature to a level that would set mortals ablaze.
At the center of this evil plane stood the city of Abriymoch, built out of obsidian and magic crystals that could resist the full power attack of Rank 8 life forms without a problem.
Inside a majestic castle at the city's nucleus stood a powerful Archdevil resembling a fiery Titan more than forty meters tall. His name was Horus, a Rank 9 Archdevil at the Initial Immortal Will Stage.
Horus' power had allowed him to set ablaze countless worlds over the millions of years of his existence. There were once sectors of the Prima Universe where his name was considered taboo and could infuse terror in even High Worlds's leaders.
