The Celestial Sanctum of Chronologies is an aethereal shrine that contains the celestial timeline records or called aethereal chronologies of a certain universe and all people in it, which is helpful in maintaining recollections of the past, present, and future. A person can only enter the shrine once he or she has the innate capability of traversing the astral plane.
This celestial shrine is located in the vast astral plane which is spiritually connected to any kind of universe. Usually, the astral travelers of Zynari can enter the shrine easily. It is because of the Zynarians' special abilities of cosmokinesis and/or astrakinesis.
