The story ends with the main character saying something in the vein of “But worst of all, she was mixed race.” I was completely floored.

The main character reads about the horrors inflicted by an underground civilization on those who break the law, try to enter, or try to leave. This information comes from a conquistador whom they’ve kept alive to gather information on the surface world. A noblewoman from this underground society falls in love with the conquistador and shares family secrets with him, hoping to escape and live happily ever after. However, he reveals that he’s just using her to escape. When they’re caught, she suffers the terrible fate he described. She’s used For vile entertainments in an arena, has her head cut off, her body reconstructed, and is turned into a zombie that guards the gate she once hoped to escape through. The conquistador is spared, though, because of his importance. Despite being warned that there won’t be a next time, he tries to escape again. Eventually, our main character digs into the mound and finds a chamber, and the story concludes with something I can summize as : "I can’t believe they did the same thing to white conquistador ".
