On the other side of the portal, make your way down the steps and along the grassy ledge. Fend off the creatures until the portal opens, then dive on through to reach the next world. They're not particularly tough opponents but they attack in large, relentless numbers. Don't get too relaxed though: a horde of sand crabs attacks a short time later. When Avallac'h comes to a halt, stop and wait for the portal to open. On the other side, follow Avallac'h through the desert.
Pass on through and prepare to enter the portal. Locate the damaged portion of the wall nearby and shatter it with a blast of Aard. When you're done, head down to the cellar and activate your Witcher Senses. Once you reach the house, follow Avallac'h inside and climb the stairs to catch up with the building's inhabitants. If you're looking for more assistance, our Witcher 3 walkthrough can help. This page covers Through Time and Space, Place of Power, Avallac'h and Ge'els.
