As one can imagine from the difference in scale, it is relatively common for an Alaereen to take a Human prisoner. However, that means that the Humans must be kept secure afterwards. As much as the soldiers enjoy personally watching over thier captives, they can only do so for so long, and it is a waste of womanpower. Putting them in holding cells designed for Alaereen isn't secure. Putting them in boxes isn't sanitary. Anyone who suggests keeping them in doll-houses isn't being serious.
Here was the eventual solution to the prisoner-keeping-dillema: a self-contained Human-holding-cell. Sized comfortably for a single prisoner, or intimately for two, it consists of a clear plastic box with an attached utiltiy stack. Battery-powered ventilation and climate controls. A water supply. And a waste reservoir. Stick a segment of a ration-bar in the cell with them, and the Human is secure for week. Or put a bunch of cells on shelves and hook up each unit to a water/sewer/power tap, and you can scale-up to an entire holding facility!
A brilliant design, marred only by a single factory defect. A misprint casued the instruction to be shown upside-down on the completed product, which always casues some degree of confusion when an Alaereen sets up her first unit...
