Can't finish quest "In the Image of the Ancients"

After getting the scholar gear pieces from the quest i go to Mor Dhona to augment them. Little did I know augmenting the pieces before finish the quest renders me unable to complete it. I have no way of abandoning the quest, re-getting back the previous scholar pieces before the augmentation. I am stuck and completely halted in leveling scholar any further.

Check the calamity salvager?

I have, but the calamity salvager does not have the pieces as i have not finished the set(having the top piece from the level 50 quest that im unable to do until i finish this level 45 one).

I feel like an idiot. i did everything EXCEPT talk to the exact same people who gave me the items in the first place. *sigh* issue is resolved.
