※ Worldview

• Age of Old Gods: Also known as the era of the Old Rulers. Eight types of rulers existed in the world, constantly vying for global hegemony. 〖The Eight Rulers〗

• Fenrir: The Beast of the End

• Hel: Jailer of the Frozen Lands

• Jormungandr: The Serpent Enveloping the World

• Typhon: The Monster Incarnate of Destruction

• Surt: The Giant Who Rules Fire

• Indra: The Thunder God of the Firmament

• Echidna: The Queen Who Birthed All Evil

• Abaddon: The Unknown Who Rules the Abyss 〖End of the Great War〗

• The stalemate of the Hegemony War was ended by Abaddon, the Unknown of the Abyss. By touching the taboos of the deep, Abaddon seized a portion of the power of 'Chaos: The All-Consuming Void,' a force once sealed away by the combined efforts of the Eight Rulers. Abaddon then swallowed the other seven rulers into the abyss, sealing them in eternal darkness. Thus, the ancient war ended.

• Dark Age of Divinity: An era where Abaddon ruled the world through the power of the Abyss and Chaos. 〖State of the Era〗

• An age of dim stability. With the war of the eight ended, non-combatant species (e.g., Humans, Dwarves, Fairies, etc.) saw an explosive population increase.

• However, the Dark Age did not last long. Abaddon's own will was eventually consumed by the power of Chaos.

• The Godless Generation of Ruin: An era swallowed by the chaos of 'Chaos' after losing all eight beings capable of opposing it. 〖Current Situation〗

• In this age of lawless chaos, a certain existence was born: the 'Undead,' beings imbued with the power of the Abyss and Chaos. They became immortal through an order warped by chaotic power, gaining the ability to grow eternally like the abyss itself. 'Grow through death, rise to fight again.' Such are the Undead. Consequently, the Undead were sent on a journey as heroic figures to defeat Abaddon, who had been consumed by Chaos. It is a long pilgrimage into the abyss and chaos that may never end. 〖Technology Level〗

• Early steam engines exist (transitioning from manual to semi-automatic). Locomotives exist, but cars do not. Furthermore, locomotives only run on specific safe sections and are not yet widespread as public transportation. Weapons include top-break revolvers, lever-action, bolt-action, and pump-action firearms. Gunpowder is black powder. It is an era where crossbows and swords remain viable primary weapons. (Dual-wielding a sword and a gun/crossbow for close and long range is the standard armament. Steel armor declined with the advent of guns; currently, light and relatively sturdy protective gear is mainstream. Magic exists but is not omnipotent, serving mostly as combat support. Pure mages exist but are extremely rare.) 〖Enemies〗

• Aberrations: Monstrous beings born from warped laws and orders caused by the power of Chaos and Abaddon's Abyss. They lack intelligence and are dangerous entities that attack people indiscriminately.

• Bandits: Savage groups taking advantage of the collapsing era.

• Cult of Ruin: A group that prays for destruction, believing collapse is mystical and the laws of Chaos and the Abyss are supreme. They are an armed faction hostile toward those seeking to defeat Abaddon, especially the Undead.
