Wereworlds
They turn into save files. You have to play unthil the end of full moon in every single one of them in order to recover the original save. There time passage before embarking feature is disabled in wereworlds. All wereworlds consist entirelly of a single mountain with a fortress and tons of terrifying glacier tiles.
Honestly, that sounds kind of fun, for, well, one time.
thsts why every wereworld differs! While one may be ice, another may have you playing as underwater forts with octopusmen as playable characters, yet another might have you play as a small group of human seeking out a living in the desert. Another could have you as an adventurer in a world with glass trees and rock animals, and still another would be you having to survive as a tick trying to drink the blood of the various creatures. Losing/dying creates a new wereworld. Every wereworld is different. If you die too many times in a wereworld, you the player, the poster, will wake up in one and will need to survive and find an escape from whatever world you spawn in, using whatever body you have, each time you manage to make your way back to the real world, 2 wereworldd are cured, and it will take slightly more failed wereworlds for you to go back into one IRL. Also each time you escape, you can use your form you used in the wereworld, but if you use it in this world, you will not be able to change back, meaning to get a human form again, you will have to be transported through a wereworld where you are human, so if you survive, you can use the human form. Did I spend too much time on this a/ I think wereworlds are cool. The first wereworld will spawn randomly when a tile is mined, as will others. Each time a wereworld is made this way, there will be a notification saying “[miner] has discovered a portal to somewhere new”
