Prieure de Sion
The Prieure de Sion has been dedicated since its inception during the Jesus Incident to undermining the power of the Knights of the Temple. In 1314, it scored its greatest victory when, with the help of Nephilim, it was able to convince the Pope and the King of France to destroy the Knights Templar.
Despite its opposition to the Temple, it is not subservient to the Nephilim. Its sworn oath is to cultivate the spiritual strength of humanity and oppose any who may seek to dominate or stifle human culture, whether they be dictators, Secret Societies, or Nephilim. They do work closely with some of the Arcana, especially the High Priestess.
