Where can I bring the Dragon Hatchling Doll to Aurene to get the mini? Story instances aren't working
If you've completed the first instance, you should have a portal stone that takes you directly to the egg chamber where you can interact with Aurene.
If you've lost the Exalted Portal Stone, you are able to purchase it from the Exalted vendor in the same area above ground where you access the underground area in Tarir.
