You need to talk to Gimdimble Fizzwoddle (titled as "an ambushed gnome") after saving him from two level 66 Doomwing ambushers. If just the ambushers are up, kill them. When they respawn, Gimdimble Fizzwoddle will be with them. Kill the Doomwing Ambushers before they kill him! ( 110, 70, 580 ) Copy/waypoint 110, 70, 580
He now starts you on the quest right away, instead of meeting him back at the crash site.
Travel to Halls of Fate and go to the center island. Head for ( -50, -400, 35 ) Copy/waypoint -50, -400, 35 and start gently traveling down towards the island bottom.
Harvest a Gnomish Dizzwangle from the very lowest reaches of the central Halls of Fate island ( -123, -771, 296 ) Copy/waypoint -123, -771, 296.
The item may not appear immediately when you approach the area. You may need to move around the area to trigger the spawn.
You will know the item has spawned when you get the message "Careful! It's windy down here!"
Make sure you collect the item shortly after you see the message. If not collected, it will despawn after a few minutes.
Ground mounts which also reduce falling speed can actually make it more difficult to maneuver down the side of the island. It's recommended you dismount for this step of the quest.
After collecting the item, you will be tossed into the air. Remember, you can steer back towards the island. Facing inwards towards the center of the island when you collect the item can help ensure you land safely.
Kill the young dragon 65^^^ heroic (quest name, no NPC credit) on the Halls of Fate main island.
The dragon is underconned and fights more like a 70^^^ heroic name. It is immune to root and mez. It also has an incredible knockback that can throw you over the island's edge if you're not careful.
To spawn the young dragon if his timer is ready: Go the entrance of the Halls of Fate at ( -2, -375, -31 ) Copy/waypoint -2.3, -375, -31. The young dragon will spawn down near where you picked up the cog earlier, and slowly fly up to his perch on the Halls of Fate building (takes about 5 minutes).
Suggestion: Keep your group at bottom of the stairs at the entrance into Halls of Fate building. Have one group member with the quest go and spawn the dragon, then run back. When the young dragon reaches its perch just above entrance, have your tank walk out and pull the young dragon inside and down to the doorway at the bottom of the stairs. The walls and ceiling surrounding the staircase will prevent you from being knocked around too far.
Return to Gimdimble Fizzwoddle. Equip the cap he gives you first with +200 safefall, then use the rocket pack that he also gave you. After a short ride straight-up and a long fall down, go speak to Gimdimble again for your reward.
