Humanity views the universe as an impossibly vast panorama of galaxies, stars and planets, each object adrift on a sea of emptiness, spreading like ripples in a pond. The Angels of the Heavens know differently --- all elements of Creation, no matter how vast or insignificant, are dependent on one another in a delicate balance of power, motion and direction. It's a grand mechanism that only God could conceive, and one that angels were ordered to monitor and maintain in perpetuity. Central to this task was the Lore of Patterns, allowing the angels of the Fourth House to study the motions of the Grand Design and predict possible problems before they occurred. Even then, the design was so large that even the Elohim could view only a small portion at any one time, leading to the creation of the Lore of Portals --- secrets that allowed the angels to travel the length and breadth of reality in the blink of an eye. Finally, like the Annunaki, whose duties would normally have kept them far from mortal eyes, the Neberu struggled to use their powers directly in the struggle against the Host of Heaven. The Lore of Light emerged during the war as the Fiends learned to use their knowledge of light --- and perception --- to weave potent illusions.
