Advances in genetic engineering, cybernetics, and other fields give rise not only to AIs, but also new varieties of humans such as superbrights, tweaks, and cyborgs. In addition, human-animal splices, animal-derived provolves, and the sapient robots known as vecs are developed. These small but rapidly growing groups join the masses of humanity. Together they are the Terragens, the children of Old Earth. Humans and other Terragens set out to colonize the Solar System. It is the dawn of the Interplanetary Age.
