Highlight setting elements

Next, identify any unique setting elements (like the Makers, the wards on the roads, the Pale Hunter, the widespread fear of water, etc.) that will play a significant role in the hook, or that would directly inform the PCs' reactions to the hook. Write a question about each of those elements, just to make sure it's something that the players are familiar with.

The crinwin are a setting element unique to Stonetop, and they'll obviously play a big part in this. They've come up a lot during introductions, but some of the more "common knowledge" details about crinwin haven't come up, like the fact that they're child-sized, and arboreal, and live in big papery nests in the trees, and that they mimic sounds. So asking about some of those might be a good idea. I jot down these questions:

• After the crinwin raid, what feature about their small, hairless, child-like bodies did you find most unnerving?
• When you've seen crinwin moving quickly through the forest canopy, what natural creature do they most remind you of?
• Remember that time you got lured off into the Woods by some crinwin? Whose voice were they mimicking, that got you to follow them?

If there's a setting element that you're pretty sure will come up, but that won't be directly relevant to the hook itself... don't ask about it yet. Wait to ask questions about it until they encounter that setting element in play, or at least until its alluded to.

Thinking about it more, the whole "crinwin mimic noises and voices" thing isn't relevant to the hook or how the PCs react to it. I decide to drop that question.

Likewise, I know that the swyn is hiding in the tomb of a mummified Green Lord, so I consider asking some questions about the Green Lords or their ruins out in the Wood. But on second thought, it's not relevant yet—and it wouldn't make any sense to ask about it.
