The Bastion of Darkness is a gargantuan fortress on the southern most pole of the central moon of the multiverse. It was created as a haven for those with dark hearts and eventually became the base of operations for several of the multiverse's most prominent villainous figures. It has seen much strife, and was even turned into a church at one time. It sits as not much more than crumbling ruins, much like its opposite counterpart, the Sanctuary of Light. Now the Wing of Nightfall, a section of the Tower of Twilight, serves as a replacement.
