Cleanse the Corruption is an Act 5 side quest, available on encountering Mogdrogen outside the entrance to the Ancient Grove in Ugdenbog.

The Ancient Grove has become corrupted by the Aetherial and Chthonic forces, and the taint now threatens to spill forth into the surrounding environment and wreak unimaginable destruction. Mogdrogen asks you to enter the Heart of the Forest and destroy the Grove's corrupted guardian.
