Magical Disciplines

A magical discipline is the most specific type of organisation we have, and the one most laypeople actually care about - nobody really cares what arcane or quantum magic actually is, compared to caring what chronomancy and graviturgy actually do.

  Magical disciplines are the single most specific form of magical organisation present across Atronach, with there being countless of them and more discovered every day. Disciplines determine the base forms of magic that actually do things, as opposed to the schools and traditions that group these base forms up into overarching identities.
  There's little in the way of rules that govern basic magical disciplines, and in many cases disciplines can develop that tackle the exact same thing, in several different ways and tied to different power sources - such as thanaturgy versus necromancy versus osteokinesis, which all deal with undeath and souls, have large amounts of overlap, but approach the matter from three very different angles that give each discipline very distinct identities. This is very normal, and there's many cases where this occurs.

Disciplined Discovery

Disciplines are the most flexible category while also being the least flexible category of magic; they're the least flexible because each discipline is very well defined and can't step much outside of this definition - pyromancy is the manipulation and control of fire and fire-based products, it cannot ever manipulate water or earth, for example - but they're the most flexible because each time new magical techniques are discovered to do things, a new discipline can be created for that magical technique.
  In this way, disciplines are constantly expanding, and they fuel the constant expansion of schools in the process to group them appropriately, and rarely, entirely new traditions have to be defined to group these schools together. In this way does the entire universe expand their magical knowledge as a unit in the eyes of the Atronach system, through which the lens of magical organisation is kept consistent across the board.

The Discipline List

Like with schools, new disciplines of magic are discovered quite regularly - usually every few hundred years. On top of that, they're also the single most plentiful form of magical component, and as such, detailing all of them is an exercise in futility. Instead, like with schools, here's a categorised list for your convenience that expands as new disciplines are discovered!
