One of many Stellazzio in the world. "Their future was uncertain, but Scorpio and Virgo kissed in the light of dusk. That moment meant everything."
Ophiuchus (オフィユカス, Ofiyukasu?), the snake-holder, also known as Serpentarius (サーペンタリウス, Sāpentariusu?), is a recurring symbol in Final Fantasy series. Though usually not counted as a zodiac sign, Ophiuchus is the thirteenth ecliptic constellation, meaning that the sun seems to pass through it during its visible route through the heavens.
Mainstream astrology uses the 12-sign zodiac, dividing the sky into 12 sectors with each sign corresponding to the location of sun through a star group. The idea of a 13-sign zodiac was propagated through the publication and promotion of a 1995 book The 13 Signs of the Zodiac by Walter Berg and Mark Yazaki, which was a bestseller in Japan. This explains the appearance of Ophiuchus in Japanese pop culture, and the Final Fantasy series. The zodiac sign of Ophiuchus was designed by Berg.
Ophiuchus is the final Stellazzio coin collected by Queen Stella. After the other twelve are discovered, Stella suspects there to be a final, secret one. It is found around the healing spring in Quan's Dwelling, in the same location the Scorpio coin was found.
The Ophiuchus Subligar is one of the thirteen zodiac subligaria, which can be obtained from a Fomor Beastmaster in specific level-capped dungeons around Tavnazia. It is used to obtain the Gaudy Harness, a light armor worn by Bards and Beastmasters.
It does not have a job assigned to it in Zodiac versions.
The 13th sign of the zodiac. All but its name remains shrouded in mystery.Zodiac sign description
Serpentarius is the secret thirteenth auracite, and is inhabited by the Lucavi demon Elidibus. Unlike the other signs of the zodiac, it does not have a month assigned in the Ivalician calendar, and so has no effect on character affinity. All characters simply react neutrally to the one enemy with this sign, Elidibus, regardless of their zodiac sign.
The stone is obtained by descending into the final level of Midlight's Deep and defeating the optional boss Elidibus. Elidibus is an unusual Lucavi in that he does not join the others in the plot to revive Ultima. Indeed, it is unknown if he has any affiliation with the other Lucavi.
A connection appears with regards to the character Unukalhai, who appears in the Final Fantasy XIV: Heavensward story line, inciting adventurers to combat powerful primals. Unukalhai is a traditional Arabic name for the star commonly known as Alpha Serpentis, which appears in the the constellation Serpens. Serpens bisects the constellation Ophiuchus, and is the reason that constellation, the 13th in the Western zodiac, is known as the "Serpent Bearer."
Ophiuchus has sometimes been used in sidereal astrology as a thirteenth sign in addition to the twelve signs of the tropical zodiac, because the eponymous constellation Ophiuchus (Greek "Serpent-bearer") as defined by the 1930 IAU constellation boundaries is situated behind the sun between November 29 and December 17.
A 13-sign zodiac has been suggested by Walter Berg and by Mark Yazaki in 1995, a suggestion that achieved some popularity in Japan, where Ophiuchus is known as Hebitsukai-Za (へびつかい座?, The Serpent Bearer?).
The Ophiuchus constellation was formerly referred to as Serpentarius, a Latin word meaning the same as its current name.
