What is Salt in Wounds?
It's a weird, gory, dark fantasy city bit around one of D&D most feared monstrosities, the Tarrasque! You can find out quite a bit about the setting here. The Salt in Wounds at a Glance and Tarrasque Flesh Golem (available for 5E and Pathfinder) pdfs are particularly interesting. Apparently the city was originally a part of an old rpg.net thread. I'm not sure if the creator of the Kickstarter was one of those original posters or if he's just someone that took the idea and run with it.
The setting has corrupt noble houses, mutants, ghouls, and mad alchemists. Judging by the bit of art I've seen and the fact the Tarrasque is referred to as a kaiju, I get a definite east Asian vibe to the city. It definitely makes me think of Hannibal Chau from Pacific Rim (and that's a great thing in my book).
The project has almost a month left and has funded. If you're looking for an interesting new setting, it is worth checking out.
