Shattered Forest

It is a forest between the Crimson Forest and the Warped Forest. It could have very difficult mobs but the mobs start to die if they go into a different biome, and players start to die when they try to enter the biome. The treasure/ loot would be awesome but dangerous to get. There could be an enchantment that protects you from taking damage in the biome but you are still vulnerable to the mobs in it. Like the name says, it would be all twisted and broken and eerie to go in. If you have any more ideas please comment and I can add them on!
