Trinities are core to most society stemming from the flock of man, and most all holy numbers of Vendrith are multiples of 3. 9 has been more of a Canathi and titan-divine number, possibly coming from the original pantheon of 9. The Sanitorium has quietly ensured the number 9 comes up as little as possible, most notably in their changing of the calendar. 21 has also been a holy number since the existence of the Twenty-One. It is believed the Twenty-Nine preceded them, but that they were reduced down to Twenty-One after the removal of the Forgotten Eight. The Twenty-Nine may have also been lead by the High Four, representing the 3+1 forms of magic - Primal Magic, Arcane, Divine Magic and Occult Magic.
