Hmmm... we probably want the duplicates to be the ones to take the stage, because it's probably going to be messy. Have them talk up just how much of a mess this code can cause if run, maybe with some warnings about how bad it would be for the area to run it immediately. You know, the kind of thing that Fentor would want to happen. Then at some point we know everything will come apart, people will attack, so on and so forth, and we arrange for Fentor's minion to get the code and it'll probably try to run it. If not... we wait in ambush outside. Sound workable?
So, a deep chime sounds in the small but luxurious Auction Theater and the duplicates of the pirates very slow raise the heavy black Girvanian-silk curtain on the motley thirty or so "early buyers" who paid significantly for the experience...
... As the curtain raises, a bizarre and very bright stream of multicolored light shines from on stage.
At this point, the three-quarters of the audience which had risen to attempt to rush the stage, hesitate and stare at a bizarre and twisting combination of a pin ball machine and a roulette wheel of spinning fire which Snobarny in sequined horse costume is operating on stage. "Come one, come all, all who would dare, the pirate code-treasure lies deep in my wonderous machine and is available to any who would play... .
From your vantage point outside the theater, the rest of the party can feel a strong magical pull from Snobarny's contraption and most of the audience members leap forward to enter the "game".
But only a few instants later, the cloaked entity you noted earlier explodes into action, beginning a terrifying babble of incomprehensible but overwhelming gibberish (an effect that sends three quarters of audience into a frothing madness ... but doesn't phase either either the sequined horse or the mechanical pirates). The thing then barrels toward the stage, engulfing the mechanical duplicate of pirate Boinga and stopping just short of Snobarny in his horse suit, who nimbly puts the machine between it and him. Meanwhile a couple of the audience member have somehow gotten into the machine and are somehow making headway towards the center where the prize supposedly is.
::Kind of improvising, I'll admit. Why not try to kill the thing? That would give it an incentive to try to "play" my game... I've added traps to make seem real-enough naturally...
The dwarf scowls at the thought he might be forced to attack anything resembling his Exalted Daughter.
