I had a nightmare persay that could possibly become a basis for an RP. In the future Females have become the dominant gender on earth due to a virus that targeted them which gave them voracious powers and destroyed male birth rate. Now the dwindling supply of men around the world lowers as many women start trying to convert men via some means like unbirth etc.. into women. There would be multiple groups in the RP such as the male resistance, the dominating women, and stragglers in between.
