Zephiris

A powerful spiritual being who, like the Peacemakers, is actually an AI (artificial intelligence) weapon created during the Genesis Wars, Zephiris is the last remaining Dragoon in the world of Providence that is fully functioning. At the start of the series, Zephiris apparently materializes in mid-air, instructing Pacifica to tell Gloria (another Dragoon who had been chasing Pacifica around in the form of a giant frog), to sleep. Gloria later turns back into her human form before vanishing. Initially, Zephiris merely give the Cassulls vital information about assassins sent to kill Pacifica, but later, it seems as if she has a hidden agenda.
