"Correct! Really, all of magic is about imposing your will on things that would be otherwise, but some schools do this more blatantly than others. Illusion focuses on pitting your will against others' wills; Conjuration focuses on pitting your will against the irresistible pull of nature itself."
"Sir, I do have a question now, actually," says Brelyna. "I thought human kingdoms didn't permit necromancy? I was surprised by you bringing it up."
"Ah, yes, a common misconception. The Mages Guild applied political pressure to ban all types of necromancy wherever it could, but those policies died with it, and were never applied in the College anyway. The College does prohibit the types of necromancy that involve trapping sapient souls into their corpses, as well as the general practice of, shall we say, creating our own materials for necromancy; those things are also illegal, although the latter is merely illegal for being murder. And, culturally, humans and especially Nords in Skyrim tend to abhor both summoning and necromancy even more than they do magic in general, for common sense reasons. It does not help public perception that many of the most notorious and destructive rogue mages out there are necromancers. As such, I recommend care when practising the Art; most people will not use Conjuration in public, for fear of reprisal, and even if it is not illegal anywhere in Skyrim the keepers of the law have historically been rather loose about this fact.

Do not move them, they should not go through space to get to you, they should sidestep space instead.
"Once you are done with this, I have a book on introductory summoning for each of you that I would recommend that you read so you can get the basics of summoning entities rather than just inanimate objects, as that is a more complex matter.
"You may begin."
