I Was a Hufflepuff, Then I Turned into a Male Zerg

My friend and I watched in terror as a group of tall men climbed down from a spaceship. For some reason, they all seemed furious. They asked how we'd gotten onto the battlefield and called us their esteemed His Excellency, the male insect. Ah... what a messed-up world.
