Thanks for the congrats, everyone, and for your stories!
I was inspired to expand this one to a longer version, if anyone's interested:
Anopheles
All creatures have a purpose.
It was a lesson we learned too late.
The end of the mosquitoes was the beginning, you see. They spread disease. Their bites itched. They served no known ecological niche. So, after many attempts, we made them extinct. We found a switch in their genetic code that caused infertility – eggs melting into gray sludge at the touch of water – and bred that variant into the population until it became dominant. They birthed one more generation and then died off all at once.
The achievement was celebrated worldwide. The team of scientists responsible received Nobel Prizes – shining medals they would later wear to their public executions.
You see, soon after the mosquitoes were gone, our symptoms began. For the most fortunate, piercing headaches and sudden nosebleeds were the worst of it. Rates of insomnia, anxiety, and self-harm skyrocketed. The most sensitive experienced sanity destroying visions.
By careful interviews, between the sobbing and screams of these unlucky souls, we pieced together a story. We learned that we were not the first technological species to call Earth home. Millennia before our ancestors crawled up from burrows, the planet hosted a race with biological sciences far beyond our own.
They had a problem much worse than mosquitoes. They were plagued by something older than the universe itself – hideous, eldritch gods, hungry for blood sacrifice. But this ingenious species found a distributed solution. They created the mosquito, and bite by bite, the old gods were appeased.
Eventually, the inventors became too proficient at creating diseases for their intra-species wars, and they destroyed themselves. The mosquitoes lived on as their most important legacy.
But now the mosquitoes are gone. And what they kept in abeyance has returned, hungrier than ever.
The ancient ones brought a message, too. They told us this, as they opened maws like the night sky and reached for us with long, sharp tongues:
All creatures have a purpose.
