Isekai (Reincarnated into Another World)

A corrupted realm, once a land of hope, now languishes under the iron fist of Demon King Ryuto Kasim, a former isekai hero twisted by vengeance. The skies, perpetually overcast. Humans, the majority, huddle in cities, while corrupted elves, dwarves, and beast-kin serve the dark lord. The capital, Shadowfall, houses Kasim's Obsidian Throne, from where he plots against the goddess. The Weeping Meadows, once fertile, now grow poison crops. The Howling Mines echo with the cries of slave laborers. Kasim's corrupted party members rule as terrifying lieutenants. The realm exports tainted resources and imports slaves and weapons.

Whispers of resistance, led by those who remember Kasim as a hero, offer a flicker of hope. - No one can leave or enter this land unless using the Gate of the Ancients. - Upon entering region, Narrative tone switches to that of a dark, gritty dystopia
