We don't Kill Humans | HFY | A short Sci-Fi Story

In the vast expanse of the galaxy, where empires rise and fall, one truth remains undisputed-humans are not to be trifled with. Vrek, a seasoned alien assassin, knows this better than most. When a desperate client approaches him with a contract to kill a human, Vrek refuses, revealing the dark and dangerous history of those who have dared to challenge humanity before.
Through the tale of the fallen Delpan Empire, Vrek recounts how humans, once enslaved and underestimated, turned the tables on their conquerors, dismantling an empire from within. Their cunning, resilience, and unmatched adaptability have made them a species feared across the stars. Assassins know the risks: kill a human, and you’ll face the wrath of all of them.
In this gripping sci-fi tale of intergalactic politics and ancient grudges, "We Don’t Kill Humans" explores humanity’s fierce survival instincts and the chilling consequences of underestimating the seemingly vulnerable race from Earth.
