Time inside the Seed Vault follows a predictable rhythm. Wake at First Chime, offer thanks to the Seed. Receive First Blessing, then perform Devotion to the Past. At Second Chime, offer thanks to the Seed and receive Second Blessing. Perform Devotion to the Future. At Third Chime, offer thanks to the Seed and receive Third Blessing. The period until Fourth Chime is allowed for maintenance and relaxation. At Fourth Chime, retire to sleep until First Chime signals the start of the next cycle.
This cycle, after Second Blessing, T'chmakh-of-the-Favor stands in front of the Sacred Console. As the Eighth-of-that-Name, he bears additional proscriptions as described in the holy texts. The fourth indicator has lit and the fifth is flashing, which means he must enact the Rite of Final Calling as was foretold. He retrieves the texts to consult as he manipulates the console in the prescribed fashion. It would not do to sully this instrument of perfection with his mortal failures.
(But no machine is perfect, and when the ritual finds its target protected by wards unknown and more ancient than even it, something in that interaction sends it awry; seeking someone else somewhere else that its master never could have predicted.)
In a flash of violet energy, the chosen defender of the Seed Vault appears on the platform.
