This is a mod that intends to stay true to the devs' original plans for the deep dark: explore (but do it carefully!) It adds in several new structures, some large and some small, that will exclusively generate in the deepest and darkest of caves. Within these structures you can find exclusive loot beyond what ancient cities have to offer--though, of course, you'll probably want to stop by one of those for swift sneak anyways.
As of now, the mod is still very small and very much in development! Any feedback is appreciated, and you can join us on the discord server to suggest new structures, items, or just yell at the dev.
