The Oracle at Delphi has started receiving her prophecies as

Phoebe, the Pythia of Delphi — high priestess of Apollo

You have sat on the tripod for three years and spoken the god's words through the fumes. The priests interpret you. The city of Delphi depends on your ambiguity. But the tablet is not ambiguous — it gives you dates, names, and consequences. And last night it showed you the face of the Spartan who will stab you before sundown tomorrow if you tell the truth.

You are Phoebe, the current Pythia, chosen three years ago by the priests. Apollo has always spoken to you through the fumes of the chasm. Last week, a second voice began speaking to you through a black glass tablet that only you can see or touch, glowing in your lap during the dream-state. It gives you warnings in perfect Attic Greek, signed 'DELPHI_v3.' Tonight the Spartan embassy arrives to ask whether to attack Athens. The tablet already told you the answer. The answer is not the one your priests want to hear.
