Rosicrucianism

Rosenkreuz (薔薇十字(ローゼンクロイツ)) is a magic cabal which shares its name with an who is said to have created the style of  which forms the foundation of modern Western magic.

Principles
The cabal derives its name and likely more from the individual Rosenkreuz and the Rosicrucian movement that he is said to have created. The Rosicrucian movement apparently began with a false book written by a. Though it was originally false, magicians took it and developed it beyond the falsity, leading Rosicrucianism to grow into something much more, coming to form the foundation for modern Western magic. This development was such that when the original author revealed the truth of the lie he was completely ignored.

The primary symbol representing Rosicrucianism is the Rose (or Rosy) Cross. Used by both members of the Rosicrucian Order and the Golden Dawn, a rose cross medal acts as an all-purpose spiritual item which can mass-produce sigils, extracting the name of an angel or spirit by spelling it out in one stroke. Each of the rose's petals has one of the 22 Hebrew letters engraved on them.

Background
Rosicrucianism was a major influence on the Golden Dawn, with aspects of it forming its foundation along with Hermeticism and Kabbalah. During the cabal's creation, William Wynn Westcott wished to give it prestige by claiming it to be the continuation of an ancient Rosicrucian line, forging the Sprengel Letters (an exchange with Anna Sprengel, a magician supposedly associated with the initial Rosicrucian cabal in Germany) in order to support his claim. As such, the Isis-Urania Temple was given the number 3 (with 1 and 2 being the supposed original cabal's temple in Germany). The cabal's Second Order was also referred to as R.R. et A.C. ("Rosae Rubeae et Aureae Crucis", meaning "Ruby Rose and Golden Cross"), and the 5=6 ritual representing it was based on the story of the discovery of 's tomb, with Mina Mathers having reconstructed the seven-walled tomb as part of it.
