Void

This data pack creates a hostile void world for skyblock mod packs.  A single piece of eternal bedrock is generated at the exact center of the build area (0,128,0) for the player to spawn on and the entire world is a custom dimension with a jet black sky.  By default only hostile mobs spawn in this biome with a special emphasis on the undead including both husks and strays.  It also was made to work with my custom sun and moon pack which can be found linked below, though you obviously don't have to use them together.
