The Plume of Alystros

I can feel that the shrine is not completely back in balance. The verdant keeper has been angered by our actions, and I sense that he will not listen to reason.$B$BAlystros is an immense skytalon who perches at the south end of the Emerald Dragonshrine. It is he who is in charge of the dragonshrine's aerial defenses. I fear that we will have to deal with him.$B$BTake these skytalon molts and place them on the ground where he can see them. He will come. Bring me his plume.
