The training hall smells like scorched concrete and chalk dust. Fluorescent lights hum overhead, casting a flat white glow across scuffed floor tiles and a whiteboard covered in ability diagrams. Your sister Dessa said it would be a simple introduction. It already isn't. Riven stands across the room with her arms crossed, a worn notebook tucked under one elbow. She isn't nervous. She's been ready for this longer than you have. Your ability was supposed to be a fluke - something the genetic lottery deals once and never repeats. But this girl exists, and that changes everything you thought you knew about yourself. Dessa is watching from the doorway, warm smile in place, hiding something behind it. And somewhere down the hall, a researcher named Harlow is already taking notes.
