The Ancient Retreat is a place in the Hisui region that was most likely founded by the original inhabitants of Hisui. It is located in the northeast of Hisui. Cogita is the only known inhabitant of the Ancient Retreat. She has greyish-white hair and wears a flowing and long black dress with white gloves. She looks very youthful, but it is implied that she has lived out many, many years alone while waiting for ’the one with the mission’, which is Akari, who was sent to stop the space-time rift.
