Tossing in a bit of Lore for the Goblins, every 100 year they go on a great Pilgrimage leaving the city-states and other various places to venture to a place that is currently unknown. It's called a pilgrimage so it seems to be atleast some kind of religious thing, but who knows it might just be a version of Burning Man. But anyways if SE does introduce a Primal for all "beastribes" (Goblins, Qiqrin, Mamool Ja currently without one) it would probably be about this pilgrimage. Also keeping to the 100 years timeline, the last Pilgrimage would have been 1572, a.k.a. the present day of 1.0. During such times, the Ascians were teaching beastmen to summon their Primal. So we'll see.
