Stoneholm Forge is a Forge port for Stoneholm a mod that adds underground villages to the world. Inspired by Strongholds and Villages (surprise, huh?).
Explore underground villages that have grown into mazes of hallways, stairs, workspaces, abandoned sections, and overgrown areas.
Backports will not be done.
Underground Villages are jigsaw structures that make use of template pools and processors as well as structure files. There isn't a ton of easy to understand information about creating jigsaw structures but TelepathicGrunt's StructureTutorialMod repo has been very helpful when developing this mod.
