Patterns are the written instructions that describe the process of performing certain types of magic. In the case of a Sage, this might be esoteric instructions along with a poem or verse that brings the spell into effect, while a Wizard's pattern would describe the meticulous and demanding process of constructing and energizing their Towers.
In any case, while Patterns might appear to simply be a sheet of paper or parchment, casually copying them by mundane means does not impart the copy with the potential for mystical enlightenment of the original version. Only with significant effort by someone familiar with the precise school of magic or academic training can imbue the teaching potential of a Pattern to a duplicate.
