Ok I took some advise from the eq2 boards from here
http://eqiiforums.station.sony.com/eq2/board/message?board.id=splitsaga&message.id=4452
It says:
Just wanted to start a thread to give a heads up to everyone of what I discovered this afternoon - That it is the CREATURES (including the Crates in the Hideout) that allow you to advance to get your GLOWING SHARD - NOT the quests that parrallel accomplishing this. So to be clear, I did 3 things and only 3 things to get my glowing shard:
* KILLED THE SOLO ARENA CHAMPION
* KILLED THE FINAL BOSS GUY IN HARCLAVE (it was the killing of the guy that help with Trust, not completing the quest itself)
* DESTROYED ALL 10 CRATES IN THE HIDEOUT IN ONE SINGLE INSTANCE (not going back multiple times to get all 10)
The key for me was to finally try out the 3rd option - Previously I had always gone in and done the DESTROY THE CRATES Quest in multiple instances (i.e. I would go in and destroy 5, then 5 more, but I had never done all at once). I couldn't figure out what was going on and thought I was bugged, but the second I destroyed all 10 crates (including the 2 hidden ones behind the cracked walls), boom, I got my Glowing Shard. To be clear, I did NO OTHER QUESTS with this guy.
I also want to clarify that I was carrying both a DARK AZURE SHARD and the new "slightly glowing" shard on me. A lot of people have been speculating that this was what was preventing them from moving forward, but now I'm guessing that a lot of people may have just not done the CRATES/HIDEOUT one correctly (i.e. destroying all 10 crates in the same instance).
I got my shard and here are the 4 spells for each class that are available after doing this.
