One of the first side quests you can find in Gerudo Desert in Zelda: Echoes of Wisdom tasks you with finding a specific hidden echo called a Flying Tile without any idea where you need to go.
The quest giver, Tormali, laments about how they are looking for a flying tile, as requested by her boss. She goes on to say that they are located in an area that isn’t easy to access, which could be anywhere around the large desert zone in the bottom left corner of the Hyrule.
