Here's what I came up so far:
-Dark fantasy, set in a medieval time with slight steampunk shit, story will be taking place on one huge continent.
-An evil god appears in the world, proclaiming that the whole place will be under his rule. Major asshole
-Humanity wages war against him, failed miserably, world is now under totalitarian rule by said god
-Hundred of years, humanity is having a shit time, nobody bothered fighting the rule
-Mysterious dude gathers the main characters, telling them that he's found a way to ascend to godhood
-Main characters do errands (quests boiiii) for mysterious dude so they could achieve godhood and defeat evil god
Let me know if you have any interesting ideas to contribute
