Vexillomancy

Vexillomancy is the practice of magic involving FLAGS, both by casting them to to produce an effect and reading their positions to divine hidden knowledge. A Vexillomancer is a practitioner of Vexillomancy, one who makes and casts FLAGS, and recruits Signifiers.  A Vexillomancer is in continuous dialog with the FLAGS during the casting, reading their positions and directing their movements accordingly.

Casting

see notable castings (vexillomancy)

A Casting is the spreading FLAGS into an area where their movements can be observed.  Proper casting involves placing the flags far enough apart that they cannot all be seen at once, while recruiting Signifiers to keep them in motion.

Signifier

A Signifier or Ensign is one who carries a FLAG, or has intention to carry a FLAG.  A signifier is continuously channeling the will of the Crystal, either consciously or unconsciously.
