The Man From O-12
PBC Sapphire's Expert System
SapphireES, or Saph for short, appears as a young blonde woman with cartoonishly-large blue eyes. She normally appears in a white PanO flight suit and often wears a pair of retro headphones, probably due to some eccentricity of one of her programmers. Despite her appearance she has no true gender, and is not self-aware. Saph only exists on board the PBC Sapphire where she is able to appear on any view screen, and can project herself as an augmented reality construct into most crew living areas.
SapphireES is one with the PBC Sapphire and has no identity without it. Although she is extremely realistic and convincingly lifelike she is not truly self aware and has no motivations or self-preservation instinct.
