The true heart of the Gurlung Colossus. The room contains a long counter with various instruments and machinery.

Overhead, a gigantic sack of dragonhide hangs in a dark, spherical chamber. It is massive. It is attached to two pipes. The pipes are controlled by a large valve wheel.

The dragonhide heart itself continually expands and contracts as it pumps oils throughout the Colossus. Oil drips from the heart.
