Centuries ago, a young Alyson Rosenberg sold her families land to the wealthy Addison family. The Addisons used the land to stage housing developments, but over time the Addisons died off, leaving only the timid Terrance Addison to continue his father's work.
In the days leading up to the arrival of Sal Fisher, a Cult known as the Devourers of God ran multiple rituals directly beneath the apartment building in an old temple where they carried out their mission to bring a demon onto the physical plane.
If was from this point forward that the apartment trapped the spirits of anyone who dies within its walls forever, including Red-Eyes.
The apartment building was going through financial difficulties during Sal's stay and still had an unfinished fifth-floor undergoing renovation after the murder of Stacy and Megan Holmes at the hands of a possessed Luke.
Presently, the Apartment has long since gone to pot and decay, with great deals of graffiti sprayed all over its exterior. It clearly has not recovered from its financial issues and was condemned.
