[Got it! So no life sized stuffed dragon-horses, stolen shipments of Kel pickles, rocket powered hoverboards, or batch of gene spliced fox/octopus embryos. I guess a well prepared cadets could have -- two tins of mixed poison/candy/assorted capsules of nastiness, (useless) stolen Andan space credit cards, a few forged IDs, a selection of weak incendiaries, three pairs of small, sharp scissors, and one square cornered inkstone with matching blowdart brushes and poisoned inksticks (although what separates poisoned from inedible is probably something that only the most distrait Andan would test, since red and gold glitter flecks are bad for you anyway). The poison (felting) needles and circular knitting needles/garrotes go without saying.

(This is a setting where "some time in the next century" is actually achievable, but, uh, maybe “within the next millennium” would be a better bet)]
