Swamped

"Creature, bog, child, something I don't recognize, book. It's in Kroskan, and I'm not that fluent, so this is probably something a bit obscure if I've decoded it right... looks like gablach, don't suppose you know what that means?"

"It means magic." You don't see a need to explain how you know that. "Archaic term for it, though, which is why it doesn't get used much any more. Strictly speaking, it refers to magic used in the service of the country. Goes back to when it was ruled by a court of wizards, you see, so they distinguished magic for personal use and magic cast in the council's name."

"Huh," Monty says. "That's weird. I guess if it reached the right person, they'd be able to figure out what it meant. Or maybe there's another message and it makes sense if you've got both."

"Well, there were some bog creatures roaming around tonight," you muse. "Perhaps whoever this note was meant for knows something about them."

Which means the person who you'd most like to question about them is currently frozen. So you should probably get back to looking for the informant. Maybe they'll be able to help you make sense of this note.

"I'll look into it," you continue. "Thanks for your help."

"Sure," Monty says. "Wait, though. If you're about to go, I've got something quick to ask you."
