From the introduction: This is the Moon Cell. A gargantuan, self-aware computer formed from photonic crystals within the moon. This immense computer has so much power that it can even warp reality itself. For millions of years, it has scanned the entirety of the Earth every nanosecond, storing all that data in its endless archives. But now, this computer has opened its servers, inviting in the humans of the earth below and giving them a chance to complete in a long forgotten ritual of the past.
