Sorey would spend a bit of time in the library trying to read up on the culture and get a feel for what the people would consider good and bad; if they're trying to prevent chaos that seems like a good place to start! What did the previous monarchs of the country do that was considered good or bad according to history? What sort of morals do their folk tales have? He'd be particularly interested in any legends/folklore that the people have surrounding the founding of their nation and the source of their water.

He would also absolutely chat up the locals for this information too, and offer to do errands or ridiculous tasks (like the fighting ring or lizard racing) in exchange for info, since he doesn't have a ton of money or water on his person.
