What was it like after hours on old Etheirys?

[YianKutku]

We don't know, all we have to go by is one place that is a recreation of the capital and another was a type of zoo/researchesque type of area far away from most civilizations.

We also have a literal dungeon for dangerous life-forms which looks like the architecture is intended to sap the morale of both the prisoners and the guards. Possibly it's supposed to be part of Elpis, but jurisdictionally it seems to be separate (under Lahabrea rather than the Chief Researcher of Elpis).

So there's allegedly some reason for keeping these dangerous life-forms around, and also the concept of incarceration (possibly including of unruly Ancients) is not alien to them. Maybe some form of drunk tank, if nothing else.
