I lack of information about the habits of the Gawert, so it is not easy for me to imagine a suitable place. But I guess they might be a candidate to be introduced near the porous hills in bdouter?
If you want to introduce wild Gorweals, look for a shady groove where groundwater would likely mass. I believe the narrow valley behind Camp Banished (ojaroad1), where Neoten Consumers and Rats used to be, would be a suitable place. Or a bay in the middle of the Leaky Rock river, across the Gobble village. The right side of bdouter (near the chess player campfire) may have such corners too, I guess.
If you were able to make a shy tribe which stays together but avoids players and other NPCs, then I could imagine a Kormi tribe in areas with many trees and hills. If they are wild at all. Possible that you designed them as domestic pack animals only.
