Petra Venj — Queen's Wrath

Loyalty to a dead Queen led Petra to the Tangled Shore. Now, that loyalty leads her to a new destination: the doorway at the top of the Watchtower—and beyond it, the Dreaming City. You're not ready to know the secrets that lie within this Awoken bastion… but Petra hopes you soon will be.

She hands you a fractured Awoken talisman and tells you to follow her into the Dreaming City by completing quest "Key of Light and Darkness."
