Industrial greed and continuous war have wrecked the lands of Stonetalon. Only the blessings of the Earthmother can cure such injury.
<name>, I will require you to seek a special seed, the Gaea seed. They are only found here in Stonetalon Mountain, north of Sun Rock Retreat at Mirkfallon Lake, near the water's edge.

You will be rewarded with the following:
The continuous destruction caused by war and those that seek a profit from lumber pains me deeply. To aid the cycle of rebirth and replenish the lands, I need Gaea seeds. Do you have them, <class>?
Ah, <name>, you have the Gaea seeds. Watch and see how the blessing of the Earthmother can cause even these small kernels of life to bloom and flourish.
