The soil of Un'Goro Crater is reportedly enriched with potent magical qualities.  The Cenarion Circle wants to study this soil in large quantities; go into the wilds of Un'Goro and acquire enough of it for our continued research.$B$BThe rich soil will stick out in piles from time to time, and some of the beasts might have usable samples on their being.  Take them all outside to Ghede; just look for the piles of dirt and the tauren barking orders.  He means well, just don't get him riled up though!
