Bendy Glass Tubes (quest)

Objectives
Bring the Bendy Glass Tubes to Deucus Valdera in Dalaran.
 * Bendy Glass Tubes (provided)

Description
You find tubing formed from a bendable sort of glass. It appears as though Grimoira was using it to suck out the insides of her victims.

Its magical properties, however, would seem ideal for use on an advanced alchemy table.

Rewards
You will receive:
 * 16,450 XP
 * 16,450 XP

Completion
What's this you have for me, ? Say, these are some wondrous tubes! I bet I know a way to make them even better.

I'll need you to temper these glass tubes in the fire of a dragon's breath under the light of a full moon on the equinox, then travel into the Emerald Dream and--

Oh, hold on. These tubes are perfect just as they are. Nevermind!

Sometimes I get a bit caught up in this whole adventuring business...
