I found these 3 in the room filled with barrels, underground in the goblin town. I sort of assume they don't like me entering the room because I didn't align with the goblins, but they don't outright attack either, so it feels like something is missing here.
I am 95% sure I looked into this room from the wall above much earlier and they weren't there at the time (the door is currently opened, so it's possible I opened it then).
Anyone know what you have to do in order to trade with them?
