The school of Illusion is a school of Philosophy focused on spells that deceive, conceal, mislead, or misdirect. It also plays with light, darkness, and color, and manipulates bits of Shadow-stuff. It is philosophically opposed to the school of Divination in that what Divination reveals, Illusion conceals.
