It's also worth pointing out that thinking purely in terms of humans on one side and goblins on the other is kind of fallacious. Once there is an actual peace mixed societies would probably emerge all over, give it a generation or two and the goblins and humans of, say, Cliffport, will find themselves having more in common with each other than with those of, say, Nowhere.
And once the interbreeding* and cross-species adoption happens, it's basically a guarantee that the two will meld into the same culture.
*This D&D, I assume that goblin-human couples are fertile. They are much closer than humans and dragons at any rate.
