The mental energy of the female priests was exhausted to a great degree, so they aged faster than regular humans and lived shorter lives, something that could be easily calculated. As such, a few or even a dozen female priests would return to the sea of stars each year, meaning that a few or a dozen successors of the female priests would come to the praying hall on the Main Planet for training.
Since it was a regular occurrence, the populace of the Federation of the Milky Way was not particularly interested in the arrival of the successors of the female priests on the Main Planet. However, the female priest of the Stargate had a very high status in the praying hall, who was only the second to the one on the Main Planet and had the same status as the female priests of the other six planetary regions. As a result, the successor of the female Stargate priest was often treated differently.
