Grey Ruins

The Grey Ruins are a set of ruins located right between Black City and White Forest in Unova. It is where the J-Team Founders fought 'M for the last time.

Access

The main method of accessing the Grey Ruins is by traveling through the sewer system that runs under both White Forest and Black City.

Inhabitants

While the Ruins housed 'M's bio core following its defeat and destruction of its computer core at the Unova League, save for some Stakataka that were placed there as a result of multiverse distortions during the Entralink Arc, it is uninhabited otherwise.
