Upon entering the ruin, a Primal Construct will spawn. Defeat it to open the gate leading further underground. Additionally, you’re able to loot an Exquisite Chest on the left after using Anemo to remove the Loose Sand Pile and a Sacred Seal on the right. After looting, head further into the ruin. Although it’s optional, we highlyrecommend following the Seelieas it will guide you to the path required to proceed with the quest.
Make sure tointeract with the mechanismto unlock the gate so you don’t get stuck at a dead end. The Seelie will eventually lead you to a room with mechanisms that shoot out Pyro, but you don’t have to worry as they won’t deal major damage. Once the Seelie settles in its Court, run straight ahead to find a room with a locked Chest.
A Primal Construct will spawn as you approach the locked Chest. Defeat it to unlock the Exquisite Chest for you to loot. Then head straight ahead and turn left to find a Dendroculus floating above anelevator. Step onto the center of the elevator andinteract with it to activate it. It will take you one floor down, where you must solve a Pyro Torch puzzle.
There are four Pyro Torches in the room, which can be activated in any order. However, start by activating the three pictured above on the room’s north, west, and south sides. The one on the right is a Ghost Torch that you need to activate with the help of the floating Tri-Yana Seed.
Waituntil the Tri-Yana Seed is beside the Ghost Torch, and then attack it with anyElectroskill. This will force the Torch to revive, allowing you to activate it using Pyro. Once all four Torches are activated, an Exquisite Chest will spawn at the center of the room. Next, you mustfollow the Seeliewaiting for you at the edge of the room. It will lead you to the front of a locked gate, which you’re able to unlock byinteracting with the mechanism.
Keep following the Seelie until it reaches its Court. Pick up the secondSacred Sealbeside the Common Chest. Once that’s done, keep going forward until you’re automatically roped into a conversation with Jeht, Tirzad, and Jebrael.

The elevator will take you to a higher floor, where you’ll find a small machine above a staircase.Interact with the machineto make friends with it and unlock the Wonders of the World Achievement calledClose Encounters of the Which Kind?After that,use the elevatoragain to return to the previous floor, where Tirzad and Jebrael are waiting.

After parting ways with the Seelie, keep following the path until you see a blue light straight ahead (pictured above). In the next room, you need to solve a Replicator Keystone puzzle.
To solve it, you need toapproach the Forged Prismal Light(floating blue triangle) so that it’s floating around you. Then step onto theReplicator Keystone(glowing platform) to force it to transform into a device. The device will connect with the opposite side through a blue line, unlocking the gate in front. Enter the gate to loot anExquisite Chest. Then defeat the Primal Construct to proceed with the next puzzle.
The logic behind this puzzle is the same as the previous one. Approachthe Forged Prismal Lightso it’s floating around you, then step onto theReplicator Keystoneplatform to reveal a device. There are two Prism Lights and platforms, so you need to reveal two devices. Then interact with the device on the left torotate it twiceor until ablue line forms, unlocking the Control Unit at the center.
