Dragon Warrior VII has two bonus dungeons that become available at the end of the game. To find them, get the Final Key from the entrance to Orgodemir's Dark Palace. Head to the Ruins and use the Final Key to unlock the gate in the room with the 4 portals. This leads you to two more Tablet pedestals, where you use the remaining ? Shards you collected. When you complete the Tablets, Travelers Gates open, leading to the dungeons. There are rare items and some very dangerous monsters. Completing both dungeons is tough even for experienced adventurers.
