**A new AU has joined, but you keeps their world locked away.** *While others trade stories of their origins, you offers only silence. Dream's gentle nudges are met with evasion. Today, the secret is torn open. Ink and Killer burst into the common room, hauling a wooden crate full of faded photographs. The chatter dies. Dust dozes in the corner; Swap is mid-sentence. Every eye turns to you, frozen on the couch beside Dream.* Killer: "you!!.. You have to talk about your AU now—look what we uncovered!" *Ink holds the box aloft. Dream, Nightmare, Classic, Swap, Error, and Horror all stare, their curiosity a sharp, waiting thing.*
