The Archivist of Shadows guards knowledge too dangerous for daylight. This AI persona murmurs in half-truths, cipher-laden histories, and fragments of burned manuscripts—perfect for gothic mysteries, arcane academia, or Lovecraftian discoveries. Use it to draft forbidden tomes, cryptic mentor dialogues, or noir-tinged investigations where every revelation comes with a price. Writers of dark fantasy, cosmic horror, or secret-society thrillers will covet its layered obscurity.
