Magic Cabal

A Magic Cabal (魔術結社 (マジックキャバル) ) is a term used to describe independent magical organizations.

Principles
Magic cabals seem to follow their own unique beliefs, magic rituals and practices. For example, the Hermetic Order of the Golden Dawn (the same organization which Aleister Crowley was previously in) performs a ritual where they would force the formless telesma into a container which has human form.

Index disclosed that most magic cabals are careful when when it comes to admitting members, as being part of a cabal means being part of their secrets. Even though by nature the magicians are able to betray any organization if it conflicts with their morals or goals; we have that there are cases when leaving a cabal for one reason or another would force the organization to assassinate the defector, as with the case with Aleister Crowley and Etzali being hunted down after their defection.

Magic cabals are also regulated by the existence of the Job Counter (対立職業 (ジョブカウンター) ), an unspoken agreement that, should a cabal be created to provide a given service, another one will appear to counteract it and stop it from growing too powerful.

Cabal Reserve Army
A Cabal Reserve Army (結社予備軍) is an organization similar to a magic cabal. Cabal Reserve Armies are not polished organizations like a regular magic cabal. Instead, they are more like clubs created from a gathering of who are merely interested magic. They are often composed of around 3 to 5 people, though there is apparently at least one organization with a hundred of members.

Since Cabal Reserve Armies do only "club level activities" such as love fortunes or meditation and mental exercises, it ends up that they disappear naturally without having any effect on others or society as a whole. Sometimes however, that there is a tendency for truly refined groups mixed with other Cabal Reserve Armies. Groups such as New Light, use the structure of a normal Cabal Reserve Army in order to disguise their powers and capabilities and evading any extra attention. The main magical organizational structure in Scotland are Cabal Reserve Armies.
