From Halopedia, the Halo wiki
- "I seemed to sense deep pulses of memory from all who had ever chosen to enter a Cryptum and were still sealed in profound meditative transcendence, united, brothers and sisters in timeless xankara."
- — Bornstellar Makes Eternal Lasting
Xankara is a state of meditative existence experienced by a Forerunner while in self-imposed exile within a Cryptum. An individual in xankara remained in deep suspended animation, with their consciousness completely immersed in the Domain in a timeless, transcendent state. Xankara was not permanent and a Forerunner would regain a normal state of awareness when revived from the Cryptum.
