Secret of the Sands is a Favor in God of War: Ragnarok. You must have unlocked The Canyons after Groa’s Secret to be able to complete it. To start it, travel to The Canyons and speak with Sindri. After talking to Sindri, ride the nearby sled all the way to The Barrens.
Your objective is to enter a cave — east of The Canyons and south of The Barrens on the map. Immediately after entering the cave, you will see a lot of Hive Matter throughout the area. You can aim your Leviathan Axe at the Purple Crystals in order to clear all the attached Hive Matter in one go. You will also need to deal with a couple of Dark Elves in the area. After you are done, climb up in the next area and clear the Hive Matter from above. You will find a Red Chest and a Rune after dropping down.
From there, use the zipline to get across and grapple across the pillars to open a shortcut near the Nornir Chest — it cannot be opened right now. After clearing the Hive Matter, climb back up in order to open another door. To get the Nornir Chest, you will need to hit 3 bells in the area. Once you are done, head deeper into the cave. On your way, you will need to clear a lot of Hive Matter as well as destroy debris (ores) by detonating the Fire Vessels.
After you get to a large lantern, you will need to rotate it to destroy some more Hive Matter. Once you are done, climb up the wall to get to a trapped Hafgufa. To free the poor creature, you will need to destroy some more Hive Matter. From there, progress forward until you see a breakable roof with a Legendary Chest behind it. After picking it up, return to sled to head over to the northwest of the area to destroy a Hive Cage to free the Hafgufa. That is pretty much all!
Once completed, you will get 1,500 XP for Kratos, 375 XP for Atreus, and clear The Barrens.
While in Alfheim, you can also work on completing these Favors:
- Song of the Sands
- The Elven Sanctum
- Freyr’s Gift
- The Desert Door
