@Mr_NutterButter i did! it only grew over time, too. it started out pretty basic, but when i started running a d&d campaign in that world it fleshed it out so much more. if you have any questions about the world/lore itself or how i went about creating it i'd be happy to tell you :)
my idea has always been to focus more on the world itself rather than the main story. that's why there are so many optional side quests and dungeons. i think the main story is about 6 hours if you know what you're doing, but doing all the side stuff i hope takes at least 3x that long just because there is so much of it, and it's all pretty unique imo.
