Humanity perfected the Alcubierre drive. First we met the Jarans, mammalian bipeds like us, except with bluer skin. Then we encountered the Ortztz, and they were of insectoid cast. And all was well. Finally, in distant parsecs, we found the Marmarians. They grew from seeds, in careful gardens; they flowered and rooted; they sang and their songs tears did wrench, they were so beautiful.
Until the Marmarians had all decent standards of ethics and morality stood. The Jarans looked like us, invoking taboo. The Ortztz looked like eight-foot high beetles and excreted through their shells; no one wanted to eat them.
The Marmarians had skin smooth and taut like a July tomato. Their hair sprang out like early asparagus. Behind them drifted a smell close to basil. We shook their hand and felt a summerfat cucumber.
We were good. We were good people. Never did we give into temptation. We welcomed the Marmarians to our world, to our city, into our homes, for dinner. We strode the Metropolitan Museum of Art with them, heard their insightful and emotional reactions to our art, listened to the tales of the beauty of their world, of its greenhouses and canals and restaurants.
All was well for the first year, until a Marmarian went missing after a walk into a Greenwich Village twilight. Another, then another. A murderer was on the loose.
They got her. They caught her with the peeler in her hand. They put her on trial, up on the stand, this poor vegan girl from Queens, and asked: Why? In the name of all that is right and good, why?
“I couldn’t take it any more,” she said. “I had to know. I had to know what they tasted like.” She burst into tears. “I’d do it again. I’d do it again!”
Our Marmarian friends were angry and baffled. Why did this happen? Were they safe here?
Of course, we replied. She was a sick, bizarre woman, and she was alone. None of us wonder what it would be taste like to make a sentient being into gazpacho. None of us have ever thought about how we might go about turning an organism that mourns its dead into ratatouille. None of these things could ever be contemplated, no matter how great the temptation.
All was well for another year, until the anthropologists got back, smuggling a walking cargo: like a Marmarian, but with skin like a rutabaga and smelling of licorice. He was a member of the Marmarian undercaste. Our vegetable friends never mentioned this. He begged asylum; the Marmarian overcaste worked his kind to death and planted their young on their rotting remains. Their entire civilization was built on slavery.
In concert with the Jarans and Ortztz, we made a formal demand to the Marmarian global government: free the undercaste immediately. They refused.
Our fleets and armies crossed parsecs to attack. The Jaran rangers, the Ortztz armadas joined with us. The Marmarians fought back, but were hopelessly outnumbered. Our troops overran the enemy, freed the slaves, executed their former masters, grilled their corpses, covered them with sauces, shipped them back to Earth for restaurants. Every mile brought new news of the horrors of the undercaste life, of the evils on which Marmarian culture depended, and made us more determined to keep fighting at long as there were Marmarians to be killed and eaten.
We cannot allow such horrors to exist. We must defend the right. It is our moral duty.
What a relief.
