Evocation

Evocation is a School of Magick that is defined by the Academia Ars Magicka et Mundana as the calling ("evoking") and manipulation of raw magickal energy.
Some academics liken evocation Magick to Conjuration that is limited to the Elemental Realms but such claims remain disputed.

Evocation is often counted as one of the most popular schools of Magick if not the most popular one as spells such as throwing flame, lighting or bolts of ice, water or acid are so emblematic of Magick that they are known to almost anybody.
As such evocation is one of the most studied Schools of Magick at the Academia Ars Magicka et Mundana.
