Ok with it fittingly being Friday the 13th I would like to introduce the sometimes hidden 13th Zodiac Sign Ophiuchus with the Black Onyx as it’s Birthstone. Over the Years some Astronomers and Astrologers have used a 13 or 14 Zodiac Sign/Constellations in the Sidereal Astrological Charts (with the 14th being Cetus) but in the realm of my Zodiac Ninja Apostle Series as of now I will use this 13th Zodiac to represent a Mysterious Force or Object often represented by the Black Onyx Gemstone. Not sure if I will ever assign any Characters to it but who knows. You can find it in Zodiac Puzzle Match!!! as bonus ‘Wild Card’ Gems you can use to Match up with the Rest and Score extra Points and Power-ups!
