Darren said:I think I got this idea into my head from the rules for copying spells from scrolls into spellbooks... A scroll definitely has an aura, and if a scroll is used to copy a spell into a spellbook, the writing on the scroll disappears, and the aura along with it.
Now, where does the magic that was stored in the scroll go, if not into the spellbook?
Well, you can play it as you want, but nowhere is it said that there's a Law of Conservation of Magic, that auras cannot simply go away.
If you must, you can consider that the magic power goes into reconstructing the full knowledge of the spell in the caster's mind, so that he can write it down.
As written, spellbooks have no power in and of themselves. They are just notation - like a musical score. Can you hear notes when standing next to a copy of the chord progression for Yellow Submarine? Do you detect anomalous electromagnetic waves near a physics textbook on electrodynamics? Why should you detect magical energy near a spellbook?
The magic is in enacting a spell. In scrolls, that action has been stored. In spellbooks, it hasn't been stored, it has merely been completely described.
