The valley was small enough that the only group large enough to have more than one settlement within was the minotaur, with one city on the eastern side, and another closer to the center, although the kobolds have more locations, deeper in the mountains, and the gnolls and hobgoblins both have routes leading over the mountains, to larger territories on the opposite side, though those routes are long and rather dangerous.<br/><br/>Truthfully, though, there were a handful of smaller 'settlements', barely more than two or three buildings, dotted about the landscape, though all within range of the central location to allow a day's journey within... or a day's journey for defenders going out.<br/><br/>The nearest civilization would actually be the elves, living in ancient-looking marble buildings, clearly not of an elven style, though it's difficult to say who might have built them.
