Bring the Rough Quartz to Canaga Earthcaller in the Valley of Trials.
Take this rough quartz from me and bring it to Canaga Earthcaller as proof of our meeting. He will craft a totem for you, and this pebble will be the heart of it. As small as it may seem, you will come to find that size does not matter, and that even the smallest of things can outlast many others.
Be patient, [player]. Remain strong. And seek wisdom. This is what earth asks of you. In the end, you shall become one with the earth--respect it as it shall respect you.
