“ A possible answer to what happens to spells when a mage dies. If the spell is strong enough, say and enchantment or other permenant effect, part of the mages spirit may become lodged in the magic.

He might have other plans for his afterlife than counting the change in your bag of holding.
Preists, I think, would have this sort of thing covered.”
