An Audience with Aaryonar

Inspect the dragon head on the second floor of The Great Aviary. This is the second last level of the palace. It's filled with ghosts.

Find the eyes of Aaryonar. Go to the Summoner's room. Climb the wall and if you go into 3rd person you will see a dragon head on the back side towards the top. You will have to go up and to the back of the top floor in order to reach it.
Next you need to go back to the room that the skylord pops in and kill the Diabolic pet guardians. Then place the feathers in the two statues on either side of the dragon bust you got the quest from.
Next kill Naar'Yora Philosophers for tomes. There are 4 alcoves on the floor below the emnity's spawn location. The placeholders are on a 12 min respawn timer.
Next you need to find 20 gems throughout the palace. There are 8 on the third floor (4 in the hallway; 4 in the main room[not the room at the end of the hall]), 6 on the fourth floor (4 in the hallway; 2 in the hatchery [room to the right]), 3 on the floor right under the green dragon with the droags, then 3 in the room with the skylord. These are clickable updates with a 1 second respawn. There are two types of beds - single and double handled. Only the single handled beds have gems.
After placing them in the bust that gave the quest, you need to go up to where the Emnity spawns and then kill him. Afterwards Aaryonar spawns. Talk to him to finish the quest.
