How to Find the Mythical Memory in Uldar
The Hár Smida Mythical Memory is found on the upper level of Uldar, in southern region of the town. You need to head into the cave to the right of the lava waterfall. There are a fair few enemies in this area so you’ll either need to sneak past them or take them out beforehand. Once inside the cave area, head down the stairs and then take the steps to the right to find a room with a large weaving loom. When you interact with the loom, you’ll trigger a mythical memory cut scene.
