The largest plant in the world, Yggdrasil was one of the first life-forms after dragons settled IIo. Yggdrasil's roots encircle the heart of the world, Wochirden, before traveling and sprouting as the Tree of Life above the North Pole and the Tree of Knowledge above the South Pole. So tall that one can easily see the curvature of the planet from its boughs, the World Tree's roots have also traveled throughout the planet to rise up as saplings on every continent.
