Dread/Spooky Dimension

A dimension that gives a player a spooky vibe when entering this dimension, there could be different biome for different themes, new blocks and new weapons armour and items, possibly enchantments, Ghost mob and a few other's to add like warewolves and dead villages, new structure's with their own unique purpose, and a boss, this dimension could connect to the deep dark and the warden that you need to go in the deep dark to get a specific item to use as a portal lighter or something like that, but if there was a Dreaded dimension that connects to the deep dark and the warden, then that could encourage players to go there in the first place to get to this new dimension.
