 * Murmur's Whisper

Description
When I'm done speaking, you may not want to take this commission.

I have an eccentric client who specializes in the study of dead realities. It is rumored that the being known as Murmur destroyed the last world from which he was summoned. The professor is interested in examining his 'whisper' as he called it to understand how it is that Murmur accomplished such a feat.

Will you journey to the Shadow Labyrinth within Auchindoun and retrieve it for me?

Progress
I'm not even certain what form a whisper is supposed to take in the physical world, but the professor assures me that you'll know it when you see it.

Perhaps it is something akin to the being's voice box?

Completion
I was worried that you might not return. I trust that you didn't go deaf from fighting Murmur?

Here is your reward. The professor will be pleased no doubt, though I worry what he ultimately wishes to do with this thing.

Come back tomorrow and I will have another request for you to fulfill.

Reward
You will receive: +  at level 70
 * Badge of Justice x 2

Gains
Upon completion of this quest you will gain:
 * +350 reputation with the Consortium
 * +350 reputation with Lower City
