The Prima Vista is the airship that Ramza bas Lexentale, his sister Alma bas Lexentale, and their father Jenomis cen Lexentale used to travel the Garlean Empire to perform their stage plays. Later, his family was exiled from the Empire so they traveled to Kugane via this same airship.
The airship is named after M.S. Prima Vista from Final Fantasy IX, the theater ship if Tantalus Theater Troupe. Prima vista is Italian for "first sight". In musical notation, to perform a piece a prima vista means to read and play written music the performer has not seen before, literally "at first sight".
