As all the Elements combined, life was formed, and Uchu was born. But, there is no life without death, and no death without fate. From birth, to growth, to death, Uchu is there.
The Garou of the Dark Time know Uchu as Gaia, and worship her. Her Aspects can been seen clearly in their mythology of the Wyld (Uchu Ascending), Weaver (Uchu Zenith), and Wyrm (Uchu Descending). Uchu Descending is not the Wyrm they fight. That is Oblivion wearing a mask to fool them. The true Wyrm is still trapped in the Web of Fate. Some say that before the Karano War, Uchu and Akeru were lovers. There is no proof one way or the other of this.
Uchu's Hidden form is that which comes after death, and before life.
