[@Dead Cruiser] I've some questions about the nature of tutelaries. 

So they're summoned from the Aether, and I know rookie sorcerers can lose control of them so obviously they have a will of their own. How exactly are they controlled? Is it like a contract where they do as we tell them, but might end up monkey's pawing us? Or are they like bound to our will and they do what we [i]want[/i] regardless of how we phrase it? 

Do they hate us?

Can they die? Is it possible/common for a sorcerer to have more than one tutelary in their career. Not at the same time, but by necessity. 

Conversely, is it possible that my tutelary has served sorcerer's before me? Can they lend magical knowledge from past indentures?
