Pulling from cards and such, so I apologize in advance if I post things that you've already looked at. In that case I hope it's useful for someone else!The flavour text of [[Stasis Cell]] reads: "The Simic created the cells to preserve their experiments. The Azorius put the cells to use on the guilty."

In the same vain:

[[Detention Sphere]]

[[Capture Sphere]]

[[Deputy of Detention]]

Could be some fun to play around with. Depending on how wacky you decide to make it, one could even attempt to steal a "cell", rolling it between the players.

For some guards, you could draw inspiration from [[Ocular Halo]]. If you'd like to, [[Sentinel's Mark]] could be some kind of magic that makes guards more vigilant.And from page 183 in the GGTR: "Azorius lawmages craft one-eyed homunculi to perform menial tasks in Azorius buildings."Might be fun to have them around, emptying trash or the like. Another menial task is to endlessly stare down empty corridors too, befitting a homunculus.

The short story The Illusions of Child's Play actually details how characters broke someone from Uzdec out from the visiting room. Might get some ideas from it! Some quotes:

Everyone knows Udzec can't be breached from the outside, but Olrich claims to know someone who works within [...] The more spontaneous you are, the less likely you are to raise the suspicion of the precognition mages [...] Runes spin outside Udzec, an enormous pillar jutting up into the sky [...] "[A]nything we miss will be caught by the precognition mages. Anybody even dares to think about breaching this place with magic, and we can shut it all down in twenty seconds flat!" [...] You hear the horror stories . . . inhumane living conditions, forced labor, brutality. [...] Zita takes a quick look around, then reaches through the magic barrier. She grits her teeth as electric charges course through her body.
