About Aldorei's Secret Quest

Hey everyone.

Recently the Wynn Team revamped the part 1 quest and i did it again (I've done both quests in the past).
I opted to choose the Elven Medallion instead of the emeralds. Now the real question is: where do i trade the medallion for the emeralds?

We're supposed to trade it after completing the part 2 but since there's no remake of it and i've already completed it i can't do a thing with the medallion.

 

You can't exchange the Elven Medallion if you have already finished Aldorei's Secret part 2. But if you've completed part 2 vefore, you already got the 2.5 LE, so I wouldn't really mind.
