Apothecary Zamah in Thunder Bluff wants you to collect 10 Serpentbloom.
The Royal Apothecary Society, based in the great Undercity of Lordaeron, has sent me here for a very specific service, [player]. Perhaps you wish to aid me, and in turn The Dark Lady in our efforts to advance the Forsaken.
Recently I studied a rare specimen of flora named Serpentbloom. I believe in greater quantities this herb has great potential.
Unfortunately Serpentbloom can only be found in the darkest recesses of the Wailing Caverns, a dangerous cave system located in the Barrens.
