Now, what is forbidden to the summoner, or any wizard, is to call a living spirit. We can call to them, yes. We can send to them a voice or a presentment, a seeming, of ourself. But we do not summon them, in spirit or in flesh, to come to us. Only the dead may we summon. Only the shadows. You can see why this must be. To summon a living man is to have entire power over him, body and mind. No one, no matter how strong or wise or great, can rightly own and use another.
