" Representations of pre-Color humans stand beside casualty statistics. One hundred and ten million died for Gold to rule. Then their bombers dropped solocene into the troposphere and neutered an entire race. Didn’t even have to convert them to the Color hierarchy. Just had to wait a century for them to die out. Bloodless genocide. Give one thing to the Conquerors. They were efficient. Pricks. "
