What do you mean by feral goblins? That's not really a thing; since their society is founded around thousands-years-old goblin dragons, goblins are actually pretty civilized. The closest thing you would see to feral goblins would be those whose dragon just died, since then they would scramble to find the next-nearest source of magic so that they can survive, but that only happens in the deserts, and we're at the Point of Origin, which is quite a ways away. You're not likely to find many goblins there, feral or otherwise.
