Ruined House

Ruined Houses are common structures generated at world creation in The Underworld. They are towers with multiple levels, constructed with missing parts for a "ruined" look, from Obsidian Brick or Hellstone Brick, along with corresponding Obsidian Brick Walls. They occur frequently but only in the middle, there are no Ruined Houses in the last 25% of The Underworld on either side. They are often partially (and sometimes even completely) flooded with Lava.

Ruined Houses commonly contain several Pots, Hellforges, Demon Torches, and several Obsidian Furniture items and decorative furniture items. They also often contain locked Shadow Chests (nearly all Shadow Chests occur within or on top of Ruined Houses), and (prior the 1.2 update) Crystal Hearts. Hellstone deposits are commonly found in the ash beside the ruined houses, making hellstone mining much easier.
