"It just - dissipates," he says. "Hmm, I've never tried storing it. The question's if there'd be any... ooh, huh. Okay: I've got enough raw power that for most applications I can think of, there's no point in hauling extra mana around to power spells, I'm not gonna run out. But there's no reason it shouldn't be possible to store a bunch of mana in some kind of - accessory, to give a Device a power boost if they're running low or want to cast something above their base level. I don't know how you'd do the same thing for a mage; the trouble is, with a Device you can design and install a system to take in the extra mana, with a mage you can't really do that. But it might be possible, who knows."
