To find the star pattern, rotate the stars a quarter-turn clockwise, then move them to the right. If you look on the map, there is one place along the northern border of Uab Nome that is east of the synchronization point where a small river bleeds into the region from the region above and this stone circle is at the bottom of that. This will also give you a fast travel point in case you ever need to make your way back to the area for one reason or another. A new event and limited-time mode will accompany the battle royale's cross-play rollout. Simply travel north and slighlty west from the town of Karanis, and the Apis Stone Circle can be found in the bottom right corner of the Isolated Desert region. This is no small feat, as you can only find Silica in Assassin's Creed Origins by scavenging many of the Tombs located throughout Egypt. In the northern section of Uab Nome, find this circle atop a rocky outcropping directly next to the northern Fast Travel point in the region.
