That explained the use of "indeterminate" to refer to the number of tiers in the initial article, when Foundation terminology generally goes "at least 50+ (exact number currently undetermined)."
The question is, did the priestess who originally approached the ASCI genuinely believe her group were containing/appeasing something down there, or was she desperate to hang onto what power she had as the head of the rites?
This is a case for Foundation personnel to point to when the new kids ask: 1) Why research all the things, no matter what, and 2) why the Foundation never takes another organization's word at face value when dealing with anomalies.
Now… can the Foundation pull people out of there, and what will happen to the pit people if they do?
