This is a world of my own creation — a realm where strength, gods, and survival intertwine.
On Terra, three kinds of warriors walk the earth: Knights, World-Knights, and the legendary Hell-Knights.
World-Knights are the first line of defense against the otherworldly. When rifts to the Hell Dimension open across Terra, it is the World-Knights who respond — entering these portals to hunt the monsters, slay the bosses, and seal the corruption. These portals are known as Dungeons. Each dungeon varies in scale and danger, some no larger than a castle, others sprawling like an entire forest. Once the dungeon's heart or boss is defeated, the portal collapses after a short time.
Both dungeons and knights are ranked by power — from F to SS, with SS being the highest.Many knights belong to powerful guilds and corporations, some bound to nations, others operating globally. These organizations forge armor, potions, and weapons from the materials found within the dungeons. Such equipment is known as World-Knight gear, crafted by expert smiths from rare, otherworldly resources.
But above all stand the Hell-Knights.
When a person turns fifteen, they must undergo the Test — a sacred trial that determines whether they are worthy to be chosen by a god. Anyone can train to become a World-Knight, but only about a hundred souls each year are chosen to become Hell-Knights.
The gods of Terra are many — both native deities and those from mythic pantheons of Earth, such as Odin and Thor. If a god selects you, you inherit their divine mark, along with a unique signature armor and fighting style that reflects their domain — a weapon, a technique, or even raw, godly strength.
Once chosen, a Hell-Knight is sent to Hell itself — not a mere dungeon, but a vast and boundless realm divided into countless Domains. Each Domain belongs to a god, and the chosen knight must conquer it. Success means returning to Terra as one of the most powerful beings alive. Failure means death.
Because of this, Hell-Knights are rare on Terra — few ever return. Those who do are revered and feared, instantly recognized as SS-rank warriors, beings who have survived trials far beyond any dungeon.
It is said that dungeons are only fragments — tiny shards — of the greater Domains in Hell. Within these dungeons lies an invisible barrier that prevents World-Knights from crossing into Hell itself. Only Hell-Knights can move freely through these boundaries; for them, the dungeon is simply another corner of their Domain.
This story follows a fifteen-year-old who stands before destiny — chosen to become a Hell-Knight. Their journey will lead them into the depths of Hell itself, where survival means defying gods, demons, and fate alike.
