Lily watched with interest and tried to come up with a comparable spell. Levitation, maybe, combined with a mobility spell, but even that wasn't likely to produce exactly the same results. "Impressive," she said once he'd come back to explain it.
She nodded when he admitted to having weakened powers. "They do that. No one's quite worked out how, honestly, or if there's some sort of pattern to it all. Sometimes some spells are neutralized, and sometimes they aren't. It generally seems to be though that the more useful you'd find a spell, the less likely it is to work."
Her brow furrowed a little when he admitted to having only three nations, since the one was wiped out. "We have ... hundreds of countries," she said. "Seven continents, though the arctic one isn't inhabited. It ... may well be that your world is smaller." She wondered if that was the case, and how it worked as far as a planet in orbit, and decided she didn't have enough of a grasp on that level of scientific knowledge to really do more than guess.
