The introduction of Hoglins and Piglins has cast new light on the lore of the Nether. It had always been assumed that the builders had visited the Nether due to the Nether Fortresses. These mobs have all but confirmed the theory.

It is assumed that Hoglins and Piglins are descendants of the ancient race of builders that settled in the Nether. Or, more accurately, were transformed into pigs after settling in the Nether. It is possible that the settlers there were transformed as punishment for their role in creating the Wither.
