I don't know how it happened. My sanity... it was long gone by then. I was experimenting with stem cells, yes, avian DNA, too, and also an odd radioactive growth hormone. I accidentally dropped them all into a test tube and created life. Knowing what would happen, I injected myself with what remaining DNA I owned.
The cops would be onto me, I knew, so I discarded my creation like an old paper towel, if you were the kind to litter. I then took up conspiracy theories as a hobby, along with technology, so my brain would have some sort of contender to prevent me from getting bored.
That night, I felt a dull, throbbing pain in my shoulder blades. I stumbled into the bathroom and took two Aspirin, but the pain got worse, and almost began to feel like growing pains. God help me, I thought, for I'm likely to burst and die! The agony began to get worse, and I convulsed. My back felt a warm liquid, probably blood, dripping down and pooling beneath me in a dark puddle in the dark bathroom. How ironic.
I felt my skin begin to tear and rend. Something extended through where my shoulder blades once were. I didn't know what it was, so I fumbled for the light switch in the darkness. After adjusting to the brilliant light, I finally got a good look at what had caused me such brilliant, exquisite agony.
It was a pair of inky black, blood-soaked wings.
