Birthed in the hollow of a tree, the forest was both his mother and guide. He knew the trees by name and the spirits within them. They became his family and he grew to be their guardian. He learned the secrets of the High Druid through their tutelage and saw that life was in balance.
Then monks of the Priestess found a spot to their liking and moved in. He watched them and saw them cure all manner of beasts and men. But when the animal population swelled and the growing number of men intruded on the land they did nothing. The forest gave way to industry and the monks moved on, deeper into the woods to repeat the cycle again.
So he fought back the only way he knew how: the law of nature and survival of the fittest. He attacked the monastery from the shadows, poisoning their crops and cutting their supply lines. When he was finally caught they branded him with a curse so he could never hide again. Whenever he intends to cause harm his body begins to glow with a brilliant light.
