aside from the grand priestess (who I believe is an important figure for the government unless this was discussed otherwise)

there should only be 24 priestesses at one time (to represent the hours of the day)

a priestess must be 24 in order to become a grand priestess.

the grand priestess' term lasts for 12 years before she "graduates" and lives with the other graduated priestesses for the rest of her life. these people are treated among the highest in society.

each of the 24 priestesses is given a number somewhere on their body (from 00-23)

if a priestess is hurt or gets sick in any way it's considered a bad omen in the designated hour that the priestess represents.

if a priestess has something good happen to her it's considered a good sign for that hour.

if a priestess becomes a grand priestess or tragically dies, a replacement is sought after as soon as possible.

priesteesses age slower than normal kronies for consuming the food of the goddess (ramen and kraft dinner)

THE ONE (represent one whole year and also only one timeline) Kronii representative, Pope like figure. Only accessible to Kronies. I would consider isolate her in a castle/church/temple in a man-made island on the middle of our great lake. Rules 24 years, when graduates it stays in the same place but doesn't have religious obligations anymore.
The 12 (represent twelve months). This are priestess that govern our religion and its institutions, so they can met outsides. They have political and cultural roles. They are everywhere on the island and can live anywhere, but should be always active on their duties.
The 365/6 (represent days): grass-level priestess, everywhere on the island and generally stationary. Everyday duties. They're teach everything a twelve should now to be able to replacement them if one is missing, steps up or becomes The One.
