Klencory

Klencory is a rock and ice planet with an atmosphere composed of chlorine and argon. The frozen surface is mainly composed of potassium with deposits of iron.

Klencory is famously claimed by the eccentric volus billionaire Kumun Shol. He claims that a vision of a higher being told him to seek on Klencory the "lost crypts of beings of light." These entities were supposedly created at the dawn of time to protect organic life from synthetic "machine devils."

Shol has been excavating on Klencory's toxic surface for two decades, at great expense. No government has valued the world enough to evict his small army of mercenaries.

So who thinks this will be involved in ME3?
