Illusion

Illusion is a School of Magick which the Academia Ars Magicka et Mundana recognizes.
Illusion as a school is made up of spells that are used to create sensory input out of nowhere to confuse the perception of targets.
Commonly created are sounds, images, smells or shadows but any sensory input may be generated and capable illusionists are able to create figments which involve all senses to better misguide their target.

A sub-school of Illusion is shadow magick which manipulates, conjures and wields shadows to create certain effects.
