"They're just kids...they couldn't activate any version of that sort of thing that I've ever heard about, but sure, I guess if you're going to qualify that there's some sort of unique magic item involved that they can use, then by the circular reasoning, if it exists, this is theoretical possible. Plausible? I wouldn't say so. If there was an unusual construct over by Digory's domicile that nabbed Lucy, that's fine, and it may mean there's some sort of Artificer mastermind behind it. Maybe the Lord of Blades: he was involved with that other schema we just got, so he's got agents here. Maybe he wanted to taunt Digory's lady friend--I seem to remember some bad blood between them. But I know that Noah left on his own and just never turned back up, so maybe he was nabbed off the street. With those two missing, did you check with Popplewell or Keynes?"
