Callista was an Artificial Intelligence created to assist Vincent Mikaru upon his joining the Templars of Twilight. She was an advanced Computer Matrix with intelligence on par with a genius level sentient being and a very realistic emotional matrix. Her visual appearance was that of a slender woman of apparent Echani decent, with silver hair, she normally wore a silver and grey bodysuit with a commlink. While appearing as a hologram she usually had three blue orbs that rotated behind her in a vertical Δ (delta shape), though they would change path and colour depending on her mood. Vocally she had a voice that was normally described as "attention grabbing" a feature probably brought about by Vincent's absent minded nature.
