Once at the service of Isis, she was stated Sho´lva by the System lords when she neglected to continue the fight against the tauri for her own reasons(She didn't believe in the system lords rule). before the betrayal of Anubis Isis was thinking about betraying her husband Osiris and dflect into the Tok´ra Coalition, because she didnt trust the System Lord Ra or her own husband. to this matter only her prime Hi´Sai was aware of this and secretly supported her. Since then Hi´Sai went into hiding and with her symbiont planned to deflect to the Tauri SGC and ask for political asylium in exchange of information about the system lords. Since then only the SGC-1 and Comander officer General Hammond Knew of her and kept her in a secret facility where Hi´Sai was training in her social skills to be more like a "normal Tauri", she finally was asigned to the SGC Phoenix squad.
