Sitting room

The sitting room is a space between time and dimensions that can be visited in dreams or in a hypnotic trance. It captures the best parts of the personalities of everyone who gets caught up with the cursed treasure of Crystal Cove.

Physical appearance
Most of it seems to be rooms and corridors with red curtains and black-and-white-striped floors, but there are doors opening out into time-frozen scenes featuring the mystery-solving groups that were pulled together under the influence of the evil Annunkai.
