Claim a supper and a spot, then. Since they have members already eating, it seems like there aren't any cultural taboos that should hold me back from doing the same.
You claim a supper and a spot. The pillow isn't particularly comfortable but is better than sitting on the floor. The stew is fatty and gamey, with chunks of root vegetables and meat you may or may not recognize as rabbit. The bread is unbearably dry unless dipped into the stew, clearly of the type that is made to last long rather than to be particularly palatable. The company isn't particularly pleasant or grating, the family mostly nods or says a small greeting before returning to their own food in silence. Their manners are not up to your standard though - you note that you where not even given a spoon, the family sipping the soup as a drink and occasionally grabbing chunks with their bare fingers and wiping them on the bread afterwords.
I look for a friendly-looking local and strike up a conversation.
You do not find anyone outside. In fact most of your companions have also disappeared. You should probably knock on either a random door or find your companions (they are probably in that house the one animal guy's mount is hanging out outside of.)
"What do you know about those nearby ruins?"
"No more or less than anyone else I suppose."
Once again the most talkative is the middle aged woman who invited you inside. The others follow the conversation attentively, but mostly just eat.
"They where a Precursor greenhouse they say. Anything we plant in them grows giant sized - like the grass you saw coming here. Grows year around too, cold doesn't bother them at all. Our little settlement could feed a big city by itself I bet. We'd all be rich if we didn't have to drag trade goods through that forest!"
Van tries to find the most unobtrusive spot to join the supper.
All spots are equally as obtrusive as the others, but you manage to put your back to the wall at least. Nobody pays you any more attention than the others.
Join the supper!
"How's life 'round here?"
"We got enough food to eat and fire to keep warm. It ain't easy but it is nice enough as long as we don't get eaten by a snake..."
At the middle aged lady's words, everyone awkwardly stops eating and looks at each other with sad eyes.
"Oh, don't be so gloomy. You have to believe they're fine. Sorry, a group of our villagers went to a dwarf settlement to pick up some new tools and they haven't come back yet. Some people are starting to think they won't but you can't live life without hope. They'll come back any day with shiny tools that we'll use for generations. Every family sent someone in the caravan...its like the village itself is missing them. Normally we'd be loud enough to scare birds for miles around at supper time."
