Rushune, also known as the Dark Master, the Evil Lord or the Wicked One, is a spirit of pure darkness and evil. He survives off of negative emotions and actions. The more cruelty and anger there is in the world, the more power Rushune possesses. He was once the Lord of the Gava, but soon after the Creation of Time, he became corrupted with power and attempted to defeat Austos and seize control of Ami. Austos was victorious and he banished Rushune from Dallanus.
