Eternal Oasis
The frozen-time oasis buried under Sumeru's Desert of Hadramaveth - locked behind two full world quest chains, with a three-memory puzzle at its heart.
You can't walk in - the Eternal Oasis only opens after finishing the Dirge of Bilqis quest chain (which itself needs Golden Slumber done). Inside, three Flower Buds lead to "Memories of the Eternal Oasis"; embed all three in the Floral Thrones for a Luxurious Chest and the "In her Full Glory" achievement.
Unlocking the oasis
- 1Finish Golden Slumber
Katheryne in Sumeru City (or Bonifaz in Aaru Village) starts it - the Jeht story chain through the desert ruins.
- 2Complete Dirge of Bilqis
The sequel chain runs five quests into the Orchard of Pairidaeza - "The Eternal Dream, Ever Lush" opens the oasis floor.
- 3Drop below Mt. Damavand
The oasis sits directly under the sandstorm - a cemetery the King Deshret built for the Goddess of Flowers.
Memories puzzle
Three Flower Buds around the oasis each lead you on a trail - touch, follow, and Activate Memory at each stop to clear blockages and reveal chests.
- 1Touch a bud and follow it
Each bud drifts along a purple flower trail - activating memories shifts the environment (unblocks paths, spawns Common Chests).
- 2Collect all three Memories
Each completed trail grants one "Memories of the Eternal Oasis" sigil - I, II and III.
- 3Embed them in the Floral Thrones
The center island's three thrones each take a sigil - Luxurious Chest plus the hidden "In her Full Glory" achievement.
- 4Bonus: three-player sit-in
Have two friends sit in the other thrones in co-op for the "A Very Long Engagement" achievement - no, Baron Bunny doesn't count.
FAQ
How long does unlocking take?
Both quest chains together run several hours - the Dirge of Bilqis alone is one of Sumeru's longest.
Is there anything else down there?
The memories puzzle is the centerpiece; the wider Hadramaveth also hides obelisk, chessboard and stone-slate puzzles elsewhere on the map.
