Illustrated backstory
Meanwhile, the transapients increase in numbers and in power. Directly or indirectly they pervade every institution, from the political, commercial and military to the religious, artistic, and scientific. Behind the scenes, a fierce power struggle develops between those who are friendly to humanity and other lesser Terragens and those who are not. After much strife, the "pro-humans" are the victors. The survivors of the other factions, the hostile "anti-humans" and indifferent or isolationist "ahumans", depart for the stars in craft fashioned and propelled by technologies far in advance of anything known to the ordinary Terragens of the day.
