Map / Forgotten Dungeon
Forgotten Dungeon
The prison under the island, off the main path and the only named area with no Wing Altar. Black Skeletal Witch Husipo holds the Dim Cell Key, the cell blocks hide a Data Module, the Sparkle Bug and a Sipeha statue, and the red door opens late for the Blood Angel Lords.
- Way in
- Optional; no Wing Altar inside. Ways in: the elevator beside the Cliff Edge monument in Verdant Hollow, the elevator down from the Tower of Knowledge basement, or the round tower off the Tower-Mausoleum bridge (one-way drops). The red door needs the Blood Angel Josami Key.
- Leave with
- Rusted Cell Key, Dim Cell Key, Sin Keeper's Spear, Amulet of the White Branch, Blood Angel Pendant (late)

Route through Forgotten Dungeon
- From the Cliff Edge monument in Verdant Hollow, ride the elevator in the room beside it to the top. The chest outside holds the Rusted Cell Key, and a Gleaming Star Lizard runs just below it.
- Past the fire pillar, jump down the pit: the Sin Keeper's Spear lies at the bottom.
- Follow the corridor to the corner and enter the room on the right. Black Skeletal Witch Husipo (3,200 Life, 130 ATK, weak to Impact) summons Cursed Skulls: kill one before she dies for its Bestiary entry. She drops the Dim Cell Key, and one of the eight Sipeha statues stands in her room.
- Leave her room and open the cell on your left (Orbewa Egg). Go back and open the cell door of the red-glowing cave: its two chests hold the Vampire's Mirror and the Amulet of the White Branch. The big red door in this cave stays shut until you carry the Blood Angel Josami Key.
- Dash across past the red cave into the pitch-black cave and walk up the slope; the wall at the bend hides a room. Go on to the brazier junction: the left fork runs through another dark cave to the Crimson Grotto monument in the Underground World.
- Take the right fork from the brazier into the cell block: the cell on the left has the orange seal of the Mundane Data Module (Orange Ochre Seal Breaker from Ossi). Through the first archway check the first two cells on the right, then activate the Pit of Despair monument in the right-hand corner past the second archway. The Sparkle Bug is locked in a side cell that the two cell keys open.
- Second way in: from the bridge between the Tower of Knowledge and the Mausoleum, jump to the round tower and drop into a small dungeon with occultists, spiders, one chest and barred windows facing the Tower. Drop through its broken floor to a second chest, the Scarlet Mimic (900 Life). The further drop into the main dungeon cannot be climbed back.
- Late: beat the Blood Angel Sisterhood by the Crumbling Fortress monument in the Rotting Cavern for the Blood Angel Josami Key, then open the red door in the red-glowing cave. Behind it are Lords Yuumed and Woyeki (Fallen Angels), who give the Blood Angel Pendant.
Come back later for

- Silver Skull high above the goddess statue in Husipo's room, with the Flying Mushroom Fossil.
- Mundane Data Module behind the orange seal in the cell block, with Ossi's Orange Ochre Seal Breaker.
