When the mirror stares back, what do you see; the lie or the liar? The Trial of Sand becomes a game of reflection. Paired against Champion Five of House Cyrinth, Seventeen steps into a chamber built from mirrors and lies. The Mirrormind's gift is mimicry; face, voice, and thought, and soon, Seventeen finds herself staring into a version of her own deceit. But reflections break both ways, and when her true power answers back, the chamber, and the illusion of order, shatter. Six champions remain. The seventh has vanished.
