The Arch Druid is always looking for additional morrowgrain for the Cenarion Circle's continued research. We take them in increments of ten, and award you with a cache of goods you should find useful. When you have ten, let me know and I will reward you accordingly.
Excellent - this morrowgrain will no doubt please the Arch Druid. I must admit though... just being near them makes me feel a little uncomfortable. I can only imagine how difficult it is for the Arch Druid to tolerate them in such large numbers!
This is for you, <name>. The Cenarion Circle thanks you for your continued support.
