Heh. Well.. I'll give it a go.
Nanork was brought up in the fierce fields of Durotar. His skin is crusty, and he has a dumb expression on his face. Through farming, Nanork got in touch with the lands, and began to very much so respect nature. His respect for nature gave birth to what he is today. A shaman. Nanork always pretended to be a mighty Shaman when he was young, he would fight all the other children in the village, and always win.
Once, whilst doing farming, he took a plant that caught his eye and ground it up. He mixed it with a few other herbs and realised it had healing properties. This also gave birth to his Alchemy. Nanork now travels all around Azeroth to bring the Horde to victory against the Alliance.
How is that?
