It was Black and White who provided the solution to this problem.
For all the power the Sisters had, they had still needed guidance.
Their parents advised and guided them, and they were able to grow.
Humanity needed mothers and fathers of civilization - gods that were like humans.
The Sisters came to the same conclusions from their parents’ fine example.
They needed to make offspring of their own, to act for them.
Though none of them had matches, or mates with which to reproduce.
Still, the Sisters each managed to produce an heir for their purposes.
In the end, humanity did receive the teachers it so desperately needed.
From Red they would receive a daughter, to teach them to transform.
From Blue they would receive a son, to teach them to describe.
From Green they would receive a man, to teach them to adapt.
