The Ruins is a dungeon-like mini-biome primarily consisting of mudstone bricks. It is useless until the player defeats the Tiki Totem boss, at which point the text "Ghosts are returning to Ruins..." will appear. The Ruins has its own unique chest that can be opened with a Ruin Key, which is dropped by Ruin Ghosts. The ruins also has a boss, the Ancient Dragon, which is summoned similarly to Golem.
