The Red Moon is a zone in ???. Geographically, this is the surface of the Moon in the Void.
Only accessible during the patch 6.4 Main Scenario Quests 
The Red Side of the Moon and Abyssal Dark, and the patch 6.5 Main Scenario Quests Back to Action, Down in the Dark and Reunited at Last.
The geography of this place mirrors that of Mare Lamentorum (specifically the area around and south of The Crushing Brand). No artificial structures are present on the surface, but a few such things can be seen looking down the northern crater (the equivalent to Mare Lamentorum’s Cradle of Darkness).
