Web of Life
The Web of Life is the term used to describe the interwoven conduits through which mana flows. The Web once connected all living things and allowed mana to flow freely throughout the world, acting much like the circulatory system in an animal. The major arteries of the Web were known as leylines and these connected directly to the Heart of the World, the Terrestrial Nexus. Since the Profound Disjunction, the Web of Life has ceased to exist, and thus the mana of the world has become stagnant.
