The Empress Den is a biome located below the Underground Desert that is created upon world generation. It is a dark gloomy biome filled to the brim with spiders, and is comprised of Weaverstone and Venomite Ore which the player will need a pickaxe with a power of 110% or more to break into the biome. The innards of the biome are comprised of multiple platforms made of weaverstone, with spider eggs and cobwebs dotted about

The biome features its own unique tiles, enemies, loot, music, and is where Araneas is fought in early Hardmode.

  • The Biome is only accessible in Hardmode, and can be quite dangerous if the player is unprepared. If you enter before Hardmode, you are killed instantly with the reason of death being "Player died of Ligma."
  • When Calamity is installed, the location of the biome is moved to the right, to not break too much of the Sunken Sea biome.
