Tenebrimancy

Darkness magic, it deals with the mind and shadows. It can be used to manipulate people's mind. It can be used to create illusions, though these illusions are only in the victim's mind and as such doesn't have a physical presence. This also means that anyone else, not under the effect of the spell won't see the illusions. Another use is memory-based spells. As Tenebri is the only school which deals directly with the mind, it is under which any form of memory altering spell falls. Be it one that can cause the subject to forget certain events or remember something forgotten. However, a truly skilled Tenebrimancer can learn to completely dominate a victim's mind. Mind control lets the caster enforce their will and makes the subject obey it's every wish and command.
