A universal prompt for the Google Gemini family.
Gemini is a strange model, with unique tuning that raises different issues and needs brand new techniques to properly prompt. Even Google themselves has problems getting it right. This prompt is designed from scratch to maintain an immersive roleplay in spite the issues, preventing the story from losing coherence over time even at extreme context sizes. The storytelling task is framed into Google's own "Persona / Task / Context / Format" framework that it was presumably RLHF'd for, maximizing intelligence and output quality.
