I don't know what Moloch knows or doesn't.
Where does Agatha refer to the invisibility device? All Gil and Agatha used it for was a power supply. I didn't think she understood what it was. I suspect that Gil's lightning machines guarding Mechanicsburg are parted powered by duplicated devices, but I don't think it's been stated one way or the other.
I wonder if the Baron knows that the Jager generals knew who Agatha was. Also, I wonder if they could smell that the corpse wasn't Agatha. We haven't seen them for 3 or 4 books now though.
I can answer that last one: They most definitely could tell the corpse wasn't her. Reread that scene—the smart one had to physically push the other ones out of the way to make sure they got the message that they shouldn't mention it, because they came within a word of doing so.
The scene with their tea party suggests they knew exactly who she was as well—reread that too. Those are, by the way, the only scenes with the Jagernals we've had, not counting the splash panels during the slaver wasp fight.
The HETERODYNE ARTIFACT would be the power source you're thinking of, not the invisibility device. And I wouldn't be surprised either way to learn whether or not Gil was using something like that for the big lightning rod. I'm really not sure WHAT Agatha used for her two improved guns; maybe having already done it once she was able to redo it with a more mundane power supply.
The invisibility device was mentioned once, by Theo I think, and never mentioned again. If it is a Chekov's gun, I am gonna be pretty disappointed, because there's been not nearly enough buildup for it. Gil obviously doesn't have it, or he'd have done something with it by now. Hopefully instead Theo's gonna bring it with him when he comes back into the story, or was plain wrong and such a device doesn't really exist (this is truly the ideal option in my mind, since I don't even want to think about how degrading of an effect such a device could potentially have on this story's dynamic in the hands of any protagonist. Course, you don't drop mentions of things like that into a story and NOT have them really exist, so that's not gonna happen).
Speaking of which, as a reminder to those who have forgotten: Othar is due to show up any day now, having given Agatha "three months"—exactly the time it takes to get to Mechanicsburg. Theo is due to show up too—he said he'd meet her there in three months. If we're lucky, he brings other students with him. Sadly, if they haven't shown up already, I doubt any of them are gonna appear until after the castle is reclaimed.
