Ancient Basin

The ruins of an ancient city at the deepest part of Hallownest. It is nearly devoid of life, hosting only scavengers and strange lifeforms. This was the original location of the White Palace, home of The Pale King, and his consorts and guards.

The ruins of the White Palace can be found in the eastern portion of the Basin.

The Abyss
Even further below the Ancient Basin lies the Abyss, an ancient pit made from corpses and Void. This is where The Pale King oversaw the creation of Vessels. Remnants of failed experiments wander the along the very bottom.

Accessible only after acquiring the King's Brand from Kingdom's Edge.

Palace Grounds
The ruins of the White Palace. Once the player has unlocked the fully Awakened Dream Nail, they can use it on the corpse of a Kingsmould on the bridge to access the memory of the palace.
