To reach this skyshard, you need to progress with the first Summerset main quest, The Queen’s Decree. At one point in this quest, you’ll be able to reach the Artaeum map and its solo dungeon, called Traitor’s Vault.
If you’ve already completed the quest, you’ll need to get back to the Keep of the Eleven Forces, located just south from Shimmerene. This is where the portal to Artaeum is now unlocked. Go through it and head left – west shortly after. You’ll soon reach a part of the compound where a blue light illuminates the entrance to the Traitor’s Vault. Go through it.

Quest to find Summerset relics is started in the College of Psijic Ruins in Artaeum. College entrance is between the entrance to Artaeum and the crafting station. Once the quest is started you will receive a Codex with clues to relic locations. The codex can be destroyed immediately if you need bag space. Then, you must do the initial Summerset Quest ‘A Queens Decree‘ which will lead you to Artaeum. Once you get to Artaeum, speak to Loremaster Celarus inside Ceporah Tower in the large room you enter (he’ll have a quest icon above his head) to get the starting quest ‘ The Psijics’ Calling ‘ to join the Psijic Order.
Based on the quantity of moldering ruins on Artaeum, once there must have been many more Monks of the Psijic Order than are present today. This hall looks to have been abandoned more recently than most.
In the delve, follow the path to your right at all times. This path will take you to the top floor, and the ruined part of the pathway, where a Bone Colossus defends the Skyshard that is looming over the center of the Traitor’s Vault.
