Objectives
Bring the Filled Gahrron's Withering Bottle to Shadow Priestess Vandis at the Bulwark, Western Plaguelands.
 * Filled Gahrron's Withering Bottle (Provided)

Description
You carefully close the spigot in the control panel, watching the cauldron's putrid ichors drip into the empty bottle.

With the poison in hand, it is time to return to Shadow Priestess Vandis at the Bulwark to complete the mission.

Rewards
You will receive:

Progress
Gahrron's Withering houses the last cauldron that we need to acquire access to here in the west. Once we have a sample of the plague from that cauldron, we will be able to introduce our reagents into the environment through four separate vessels! The Scourge will be hard pressed to keep us out of all four, even with the power of Kel'Thuzad behind them.

Completion
Congratulations, you've unlocked the last cauldron for us! Apothecary Dithers will soon know what this cauldron requires as far as reagents needed for the mix.

As for you, I am sure that High Executor Derrington will want to thank you personally for the assistance you've given us. Without you, our struggle against the Scourge would have been nearly insurmountable. I thank you, mighty.
