The Cycle of EnergyIn nature, there is a cycle of magical energy that occurs. Magical energy is provided from the heart of Etharai through bloodlines, and then flows into the earth, or sometimes absorbed by certain creatures. Then, the magic is used for a number of different things: it may be used for movement, growth, or hunting. Carefully done, it can be harnessed by people.
Regardless of how it is used, it use then causes excess magical energy to exude from the creature, in the form of an Aura. Once this energy disappates, it is soaked back into the bloodlines and is returned to the heart. There, it is used to re-energise the heart as more energy is pumped out.
