The Elder Scrolls universe has many animals and monsters, many of which could very easily be trained. Would you like to see the ability to train animals and monsters to help you in battles? I could see how too many animals could make the game too easy, so they could limit it to three animals out at a time, the others could be summoned maybe? Perhaps a special flute and a certain tune would summon a different animal?

Yes.Illusion magic is perfect for this.

Gotta catch 'em all!
