Fading into Twilight

If you did not do the quest chain in stormwind to get here, go back and do it.... opens up all the quests I needed to finish!

I got stuck at 104/120 on this. A useful download I found was an addon named Questhubber, however my Carbonite was overwriting the map update the addon was providing for available quests. Suggestion to all: Install the addon, disable your Carbonite temporarily. Find the quests you need to do (marked with !), if you can't figure out where you need to go, you can reload your Carbonite on the fly. To see the quests available through Questhubber though you will need to disable Carbonite again. I'm currently at 112/120 now, so it seems to have helped. Good luck with your questing.

If you are level 120 and haven't done the Fading into Twilight achievement, you have to pick up the quest Twilight Shores given by Grand Admiral Jes-Tereth. She stands in Stormwind Keep next to King Anduin Wrynn. This is the only way to start the quest lines in Twilight Highlands at such a high level as far as I'm aware.
