It refers to the twelve zodiacal constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Ophiuchus is also a zodiacal constellation, though often not counted, but most games in the series that include the zodiac make note of it in some way. The thirteen signs of the Final Fantasy zodiac appear on the Ivalice Alliance logo. The summon Zodiark is named after the zodiac.
