Add more to the deep dark

I found that it was super fun and scary to walk through the deep dark trying to find an ancient city. It was cool having to be super cautious and not being able to place torches, being in complete darkness. But I dont think there are enough reasons to explore the deep dark, players arent really encouraged to explore the deep dark much unless they can directly see the city. I think to encourage players more there should be more special buildings in the deep dark, like a mob spawner that is infected or something and gives special loot and spawns special mobs. More structures would make me want to explore and interact with the deep dark more.
