Obtain the Fading Memory Glass from Devos, Paragon of Doubt in the Spires of Ascension.
You have, no doubt, visited Bastion and seen what happens to souls that are accepted there. Their memories are extracted, viewed, and even stored in their great Temple of Wisdom. This temple houses memories that may answer some of the greatest questions we have about our realm and the worlds beyond. It is a shame they are locked away. We have heard that the fallen Paragon of Loyalty has interest in these memories. Any memory that would catch her attention would surely be worth trading for.
