Incarnation are an esoteric magic traditions that works through incarnating supernatural entities within themselves or in others. By opening up their bodies to the spirits, the incarnators gives himself supernatural abilities of all kinds.
Incarnation is a dangerous type of magic, and the sorcerer often risks coming under the sway of the forces he tries to use.
Note that incarnators are rarely actually possessed in game terms. They allow spirits to manifest through them, which gives them the ability to work sorcery and causes echoes as the spirits try to resist. But they maintain their own free will in most matters. Of course, there are always backlashes and exceptional situations.
