Use the Herald's Incense before Aviana's Egg at the Shrine of Aviana.
I'm convinced that YOU are the herald of Aviana, <name>. It was you who first saw her and rescued her essence from the claws of a dragon.
Yes, I believe Aviana is to be reborn into our world. And you shall have the honor of ushering her over the threshold.
Take this incense and burn it before Aviana's egg in the room just above me.
The ancient awaits, <name>. Our deliverance is here!
