Walkthrough of the quest The Riddle of Sea and Sky

How to start

The quest should appear in your journal immediately after completing the previous mission, "Where the Koholasaurs Gather". If this does not happen, try logging out of your account and logging back in after 20-30 minutes.

Go to the place that Mualani discovered through analysis

Head southeast from the Archon Statue in the waters of Ameyalco. Viramdra suggests that the stone platform where you find yourself may contain Dragon Spirit Doors, or Phlogiston Nodes - ancient devices that will help you find the mysterious island.

Activate the first phlogiston node

Go to the island south of your location. If you opened a teleporter there beforehand, you can teleport there right away.

Also, to reach the island faster, you can inhabit the Koholasaurus Soul Beacon.

Climb to the top of the hill. You will find the first node, but it is too high.

Break the mountain of rocks next to the stone pillar.

Activate the blue mechanism by attacking it.

Follow the opened path and touch the node at the “Upstairs”.

Activate the second phlogiston node

From the first node, fly southwest. Defeat a couple of Hilichurls and touch the second node.

Take the Spiritual Path Test

Once you have control of Mualani, use her elemental skill.

Move along the spiritual paths, jumping over obstacles. When the path ends, use the jump and turn right to move to the next path.

When a new path appears, jump to the left.

Use the Phlogiston Knot to change routes

As the Traveler, climb up to the next Phlogiston Node and touch it.

The path you will find yourself on is a closed circle, so at the right moment, jump to the path on the left.

After passing several obstacles, turn left again.

Use the phlogiston node again to change routes

Touch the third node while playing as the Traveler.

Once you're on the new path, jump to the right road as quickly as possible. Overcome a couple more obstacles and reach the end.

Explore the maelstrom With You Mualani

Spiritual paths and map clues will indicate that the mysterious island can be reached by entering a huge whirlpool. Viramdra will decide that this is dangerous - to prove otherwise, head to the northern edge of the island.

While you are discussing the dangers, Viramdra will decide to test his own theories and will be carried away by the water.

Save Viramdra

You have to swim to the scientist in a minute and a half. Activate Mualani E and follow the phlogiston seeds, jumping over obstacles and avoiding whirlpools.

There will be blue circles in front of some obstacles - stand on them to jump higher and collect seeds.

Help Mualani set up camp

Once Viramdra is rescued, the whirlpools will disappear. Your guide will suggest setting up camp and resting. Approach Mualani and the scientists and set up a tent.
