The Silver Thread: Draco Dream Simulator is a playable Harry Potter otome visual novel set inside a moonlit Hogwarts. You arrive as a transfer student with your own name, house, year and first impression — and the moment you step into the night corridor, Draco Malfoy is already waiting, holding a silver crest that carries your name.
Choose your replies, investigate the crest, and unlock the classrooms, the restricted library and the Black Lake. Watch the relationship map redraw itself as trust, wariness and secrets quietly shift, and fill the archive with the illustrations you earn. Every scene is written live as you play, so no two runs read the same.

Game Features
- Live LLM Narrative — Every line of dialogue, every glance and every reveal is written live by the narrator as you play. The deepseek-v4-flash narrator voices Draco, Pansy, Blaise and Hermione, sets each scene from your answers, and remembers every choice you make across the chapter.
- Create Your Own Identity — Name, house, year and a first-impression trait are yours to choose. Your identity is not decoration: it changes how the castle addresses you and how far Draco lets you in from the very first corridor.
- The Silver Crest Mystery — An unsigned invitation and a silver crest that carries your name. Follow the clue through the moonlit corridor, the restricted library and the Black Lake to decide whether it is an invitation into Draco’s secret — or a place in the Malfoy family’s plan.
- Choice, Investigation & Unlocks — Every reply moves three hidden tracks — trust, wariness and secrets. Investigate new events to light up fresh locations on the map and unlock the relationship graph, node by node.
- Relationship Graph & CG Archive — The Hogwarts Archive charts Draco, Pansy, Blaise and Hermione as routes you unlock while you play, and the album fills with illustration cards for the moments you earn.
- Browser Playable — Save & Restart — Runs directly in your browser with no download. Switch between English and 中文, save your progress, or restart to chase a different trust or wariness ending.
