You must be able to speak Gnomish to accept this quest.
Starting the Quest
You need to talk to Gimdimble Fizzwoddle 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.

Return to Gimdimble Fizzwoddle
Kill the Young Dragon on the isle
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.
Some people who have succeeded in completing the quest recommend you have an outside group to help kill it. The dragon has been soloed, however, with, for example, a 70 level necromancer.
To spawn the young dragon if his timer is ready: Go the entrance of the Halls of Fate at ( -4, -376, -33 ) Copy/waypoint -4, -376, -33. 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.
