Editing Space Harpies (section)

===Medieval Period===
During this period, chemistry became more and more common, and recreational drug use became exceedingly common amongst the upper classes. Gunpowder and rocketry were discovered far earlier into Harpy history than human history because of their focus upon chemistry, with highly dangerous explosives becoming exceedingly common amongst the front line troops. A system of proving one's worth on the battlefield soon became standard, as single males found a new avenue out of bachelorhood (and thus slavery) through service to their lords. Troops would proceed to the front lines and ignite highly volatile, unstable, and flammable rockets and fling them into the enemy lines, or into their forest homes, burning them and killing many. Any who survived soon found themselves under the attentions of the females of the species, often allowed to marry into the noble caste and start harems of their own. It was at this point that the formalized enslavement of single males would have begun to end, and instead a voluntary system of 'proving oneself' became the norm. After a time, it soon stopped being a feudal system, but a meritocracy where even males of high noble birth could not expect to be given an advantage.

Drugs were often used to induce estrus, to quickly produce more citizens for the constant bloody warfare seen between various tribal and feudal groups using black powder weaponry. Harpies experienced the devastating effects of mass artillery warfare, as was experienced by humans in the United States during their civil war, around the same time they invented the printing press.
