This world has a population limited to a volcanic island chain and a nearby region of mountain and savanna. They have magic not much like any the Institute are familiar with, with use of the magic increasingly common towards a particular region within the range of people, but some magic occurring even where there are no people.
"I'd be curious to see what your fish traps look like, if you have any around the village. I'd also be interested to hear about what plants and animals are useful around here. We're from quite a distance and so we're not familiar with what is around here."
"Slow, after Sticks shows off her eel traps do you want to show the strangers what plants they can eat"
Sticks enthusiastically shows them how she makes a fish trap and describes how she would put it in the river. The traps are extremely primitive.
He asks several clarifying questions and suggests some possible avenues for improvement.
Sticks is happy to answer questions and take on suggestions. And after they finish with that Slow and two adults called Big Nose and One Eye (the latter of whom indeed has a missing eye) will take the explorers into the wilderness and point out some edible plants.
Alice takes samples of those and various other plants and puts them into vials she retrieves from her backpack.
Zabna asks questions about how often the plants can be harvested and how much of their food the tribe get from them.
Plants make up around a quarter of this community's diet. Considering that nothing is cultivated there is an unusual lack of anything that needs preparation to be edible, although Slow does comment on how some plants are best cooked.
