Minecraft wiki entry for Before_Village_%26_Pillage, associated text: Nether portal: If portals have not already been constructed in the Nether, then the player can create a portal at the Overworld destination, travel into the nether and back out again immediately, then build another portal in a village less than 1,024 blocks from the first portal. After pushing villagers into the village portal (manually or by minecart), then pushing them back out again, letting them "cool down" for 30 seconds, and pushing them back in, the villagers should exit from the first portal.[verify]
