Those three stipulations should not be a problem for me.

I will make sure to be cognizant of limits for Henry's abilities.  Adapting the durability system from Awakening to give the tomes a certain number of 'uses' before they're depleted and must passively recharge is one way, but I'll also tie the casting of magic to Henry's being as well.  The dark arts will have a negative effect on Henry corresponding to what they do to others.

I was curious about the lack of a personality section, actually.  In my eyes this is a necessary adjustment, and I'm happy to add to my sheet while you continue to work the RP together.
