Illusion Magic is an uncommon Talent involving tricking the senses in various ways. Someone who practices Illusion Magic is called an Illusionist.
The aura color typically associated with Illusion is lavender.
The most common ability Illusionists possess is creating intangible images in the air. A poor or unskilled Illusionist may wind up making illusions that are unconvincing or partially transparent, but a more skilled one may simply do so to use them as a representation of something, such as creating a diagram in the air, rather than actually attempting to fool anyone into believing it is real.
Basic illusions are simply light and color, without substance, heat, or sound. To add those components to an illusion, the mage must combine it with other Talents. Using telekinesis will allow the creation of solid illusions, for instance.
In addition to creating images, a skilled Illusionist can also cause sounds. This ability is sometimes grouped under Speech Magic, but unlike Speech, it does not involve the caster's own voice, and may not even include a voice at all. The creation of sound may be voices, yes, but it may also be music, or weather, or the sound of movement, for example. Sound magic may be used to add an auditory component to an illusion to give it more authenticity, or to give a vocal message to someone.
In addition to light, Illusion Magic also covers the absence of light. Shadow Magic can, as the name might indicate, cause supernatural darkness, blacking out an area that would otherwise be lit.
Shadow Magic can be used to hide and conceal people, places, and objects. It is easier to make something invisible when an area is already dim or obscured, but a sufficiently skilled Illusionist can cause a subject to vanish from the senses even in the midst of broad daylight.
