From the introduction:
In the beginning, the Cosmos functioned well. A looming presence known only as Management kept things running smoothly and coolly. This was partially because The Management was a dedicated worker at the beginning of time, partially because there was nothing to manage besides a couple rocks and space.
The Management decided to create a force of beings to assist it in running the universe. Thus, the management created Gods.
The Gods created the worlds, and brought forth life to fill these worlds with. They sculpted, with great care, landscapes and life forms.
The first Gods, The Prefects, realized that managing these burgeoning life forms was outside their own means, and birthed a new order of Gods: The Marshals.
