The Mechanical Mine is a link fluid mine located underneath the Phantom Pit where labor monks excavate link fluid for the Infinite Empire, many of whom have mutated after prolonged exposure to the fluid's toxic fumes. The mine is a network of tunnels and scaffolding, whose entirety wraps around a large lake of link fluid. Valor enters the mine in search of Marty, and finds her on a small island in the lake, after draining the bottom level of the mine.
