▸ Present a discovery
Discoveries are interesting things that the PCs find but that aren't inherently or immediately dangerous. They might be useful or valuable, or just something mysterious that's worth investigating. See the Discoveries chapter, starting on Discoveries
When you make this move, you just put the discovery in front them. Describe it, tell them what they see/hear/smell/feel, what (if anything) it does. Make it clear that this is something of note. What they do next is up to them.
"Blodwen, while you and Vahid wait for the others, the wind picks up and starts tossing puffs of snow about. But then you realize that, no, those puffs are a little too intentional, and you hear—no, more like sense—a laughter in the wind. There's a wind spirit flitting about. What do you do?"
"Yeah, Vahid, now that you're closer, and looking up at it, you can see that it's definitely a nest. A papery thing, like a wasp nest, but way, way bigger. This must be what the crinwin live in. What do you do?"
