Upon looking over the items you received from the vault in the Sanctum of the Scaleborn, you find a note that reads:
Cyenadros, see to it that this crystal is destroyed after viewing its directive. We cannot have just any earth walker prancing in here and dunking this gem into the spirit pool. - High Priestess Harla Dar of the Awakened
Steps[]
Examine the crystal of command, also received at the end of the previous quest.
Go to the Pool of Spirits ( 152, 41, 146 ) Copy/waypoint 152.4, 41.1, 145.5, and jump into the pool. Examine the crystal again to get the first update.
A certain spot on the pool can be interacted with. Right-click and throw the crystal into the pool.
Within 90 seconds, speak to the 'Voice of the Palace' who has spawned at the bottom of the pool.
If you betray your city any time before starting this quest you may be unable to complete it, as it will send you to the wrong NPC, who will not talk to you. Different players have reported different results, so do not betray before this step.
UPDATE & WARNING for Varsoon Server (2023-Jan): Petition will not work. The GM will tell you to betray back to finish this quest. You may be required to buy another Betrayal Token, or go through the whole betrayal process.
