Slumbering Roots is one of the quests in the Varuna Gatha World Quest series, also known as Varuna Gatha. The next three quests in the Varuna Gatha World Quest series can be completed in any order. The last quest in the Varuna Gatha World Quest series, A Prayer for Rain on the Fecund Land, takes place at the Grove of Dreams in Sumeru's Ashavan Realm.
Where can I find the entrance to the Grove of Dreams?
Follow the marking, and when you get to the quest area, locate the entrance to the Grove of Dreams on the north side. It's basically a hole in the ground next to a small stone circle. Glide down into it, then follow the tunnel back to the marked location. Here you'll learn how to play the Rhythm of the Great Dream. This is the song you've first played during the World of Aranara quest.
Continue on to the grove, using the bouncy mushroom to help you get up to the roots. Continue on until you reach the large fungi platforms on the left, then climb up to Silpna and play the Rhythm of the Great Dream for a second time.
Where to find the three leaves
The first leaf is right next to the branch, so rotate it once to turn it toward the branch. Follow the ledge north then east, then glide down the lowest level of the grove. These monsters will guard this third leaf, so defeat them and rotate the leaf once more. Return to Silapna and complete the Slumbering Roots quest.
