From the introduction:
Imagine a lone planet hurtling through the darkness of infinite space. Something crushlands on said planet, which we shall call "Earth". This something oozes and bubbles, eventually splitting into various entities that defy Euclidean Geometry and also spans forth what will be known as Humanity.
You are these Slime Octopi, the planet is the Coral upon which you have taken residence. Humanity is your goal, Humanity is how your goal will be achieved. Humanity is the means to your destruction.
