Andy is correct. The goblins fled North, deserting their liege. They should have fled South into Elinie for protection.
They chose the wilderness and from that point on, the Patriarch dropped all plans of letting goblins have their own provinces under his protection.
He remains convinced that the other intelligent species has valuable insights that humanity would do well to learn. - And fundamentally believes that all beings should be judged by their word and actions rather than their species. Of course he has also learned not to flaunt that belief in the face of certain temples and nobles.
I would just note that the 'he' above is the Patriarch, Robhan is far from convinced that the other allegedly intelligent species have valuable insights. Orthodox doctrine is clear that most of these beings are of course divinely disfigured due to sins committed by their ancestors against the gods, the misshapen brutes remain on Cerilia only to provide humanity with proof of the superiority of man, provide him with servants or to test his worthiness. Certain more extreme tracts make similar claims regarding peasants of course ... :-)
