A Magic Sequence (魔法式) is an information body constructed from a Magician's Psions. When a Magic Sequence interferes with, and overwrites, an Eidos, it can alter real-world phenomena. However, because of the world's restorative power to maintain temporal continuity, magic sequences cannot be used infinitely. [1]

Magic & Activation Sequences

An Activation Sequence (起動式) is a magic blueprint constructed out of Psions by the Casting Assistant Device (CAD) used to jump-start construction of the Magic Sequence. It replaces the mediums used in Ancient Magic and allows faster and more efficient use of magic. Once an Activation Sequence is constructed, it is absorbed into the Magician using their body as a medium and then sent to their mental system, Magic Calculation Area(Magic operation zone) where some of the necessary variables are filled.

  • The psion initially produced by the user is unable to cause "interference" as they would just scrabble and return, hence to affect reality their form and structure needs modification. This is the function of CADs, to take the Psions initially produced to construct the Activation Sequence, and form them into Psions the Magician can use to rewrite phenomena: the magic ritual (sequence).[2]
  • The Activation Sequences are digitalised magic circle blueprints stored in the CADs in compressed forms. they contain variables such as coordinates, output, and duration. It is then sent to the Magic Calculation Area, processed were other variables such as targets and strength are inputted, and then the spell is assembled and activated.[2]

This is Modern-day Magic.

The Activation Ritual (sequence) is a large block of data for building a magic ritual. Mages can intuitively guess what kind of effect the ritual would have. By looking at how the magic ritual (sequence) would interfere with the Eidos, and what parts wouldn't be affected, it's possible to read and attempt a guess at the effect the magic ritual would have. However the activation sequence alone is simply a chunk of data, representing a massive amount of information, and even the magician deploying it can only dynamically interact with it in the subconscious. Therefore, the act of reading the activation sequence requires the enumeration of endless strings of image data, then reproducing an image from those in your head. Normally, such things cannot be done in the consciousness.

Directly trying to interact with Psions produced by another magicians activation sequence will cause a rejection by the other magicians' subconscious.
If a magician "A" places hands on a magician "B"'s CAD while the magic is being cast, then magician "A" will receive the interference 1000 fold (times). ​​[2]
