The universe beyond is called the Abyss, and every 100 million years of the universe's life is as fleeting to the Abyss as a bubble in boiling water. When the time comes, the tide of the Abyss will flood the universe, bringing the dead Eyger back to the Abyss, and bringing new Eygers with them to fight for the throne—armed with the remnants of the civilization that once was, Eygers battle to determine a master and begin a new cycle. This ritual came to be known as the Chaos Party.
