Cocytus

The Cocytus (コキュートス, Kokyūtosu) is is an area connected to all Dark Areas, with each Digital World having its own Dark Area. There is only one Cocytus, with the location shared by every Dark Area, with Cocytus acting as the deepest layer within each Dark Area, connecting them all to each other. Grand Dracumon, Gulfmon, and the Seven Great Demon Lords have their castles and base of operations here.

=Appearances=

The Seven Great Demon Lords take residence in the Cocytus. Lucemon (X-Antibody) had Keramon (X-Antibody) wait in the Cocytus and after the Demon Lords were defeated it teleported their bodies to the Cocytus and then had Keramon warp evolve to Diablomon (X-Antibody) and fuse with the bodies of the defeated Demon Lords to create Ogudomon (X-Antibody).
