Concealed Ruins (Japanese: かくされたいせき Concealed Ruins) is a dungeon in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness. It is unlocked after defeating Regigigas in Aegis Cave. When the player exits Aegis Cave with Team Charm, a new entrance to the treasure opens, Concealed Ruins. It consists of 30 floors.

Raikou can be found on B20F, but the player needs to have the Mystery Part or Secret Slab in the bag. There is a locked door on B29F with a possibility of a box containing either Rock Sash, Steel Sash, Ice Sash, or Ancient Ring. At the end of the dungeon, there are six Deluxe Boxes and a Warp Tile leading out of the dungeon.

  • Within the game's code is a location called Deep Concealed Ruins, implying the location was initially meant to be split in two parts. However, the game loads data of the Test Dungeon instead.
