"Over the epochs she had thought she had seen everything. But nothing, not even those early days when she had to watch over her sister negotiate the furious eons of her fiery youth, compared to what she was now observing." Bang! And the universe is born.
And in a thoroughly non-descript part of the cosmos, eight wanderers, including Gaia and her diminutive satellite sister Luna, are placed by the great creator.
Then one day, Gaia announces that something has happened to her, something that she has called 'Life', and the two wanderers begin to study and curate and nurture this strange new phenomenon.
What wonders they witness, and what strange new concepts they discover as the Life evolves and diversifies at a breakneck pace.
Latterly, they observe the rise of a curious species of ape, the first emanation of Life to attain sentience and self-awareness. And as they follow and chart the rise of this ape to domination of the entire world, they become increasingly concerned about the behaviour of this 'wise' species, what it is doing to Gaia, and what might happen to them all as a result.
