Tartarus (mini-biome)

Tartarus is a mini-biome that appears in the Underworld once [War Mode] has been activated.

Generation
Tartarus is generated in the Underworld in one of the outer-thirds of the map. It always spawns on the opposite side of where the player is standing. Tartarus won't affect the Underworld much - it only replaces the blocks with Tartarus-special tiles.
