Ivern Bramblefoot, the Green Father used to be a powerful warrior until he was cursed and become what he is now. A walking tree. Now he roams the forest's of the world bringing life to everywhere he goes and to protect nature of humans and other terror of the world.
Ivern having to be a tree he basically is the embodiment of Importance of nature. His life before had him as a powerful warrior but now he now lives as tree. With this he now lives a new life as a tree which is his redemption in his new life. The quote also fits him because he now lives in the forest making new life as a whole and saving life as well or nature.
