disclaimers: this isn't all my story ideas + the character art is generated through an image generator called picrew (not an ai thing but everytime i see image generator i think ai now. its more like one of those dressup games)
a story about the worst sinners in the entire universe, and especially a gang run by the six kings of the sins. can't think of a linear plot outside of that (could be them finding out what happened to the seventh sin, pride, but idk). for the people who read scrapbook sacrament, athal is the afterlife but explicitly for the worst sinners (whereas effervian is more so 'general dead people')
a story about a detective and his friend solving various crimes. not too sure how to turn this into a proper story (could be about a proper massive crime) because it's currently written as a short story series. i could try and link the crimes together maybe?
a story about a group of characters living in an apartment building/townhouse complex? are put through a social experiment and are forced to kill each other. the last person alive survives and is rewarded.
a story about someone who survives a shark attack and wakes up a half shark. they think it's the creator of the universe's fault (surf, who is an anthropomorphic shark) and set their whole life goal to be to kill surf to sort of get revenge (he thinks it's a cruel joke like 'haha i revived you and made you a shark'). also they get four lives because the other gods think this mortal trying to kill the creator of the universe is funny as fuck so they let them have multiple goes. probably has a bit of a groundhog day-esque theme of learning to appreciate life
a road trip through the entire world. it doesn't have a strong plot (mostly things like friendship rivalries, romance, basic road trip stuff. tips to spice this one up encouraged! also they're all anthropomorphic animals.) bonus info: this is what scrapbook sacrament was originally gonna be!
okay this story would be huge and definitely not finished in a year but! it's a sort of massive sweeping world building thing that explains the history of the entire universe i'm writing. it'd be a massive project but i do have a lot of planning for this one so maybe?
