Fred pushed back a curtain beside the Muggle tricks and Alani saw a darker room. The packaging on the products lining these shelves was more subdued. "We've just developed this more serious line, funny how it happened... You wouldn't believe how many people, even people who work at the Ministry, can't do a decent Shield Charm.

Fred explained, Alani listened to him intently he had never had anyone so interested in what he liked before. "Have you tried reversing that? Making spell repelling rings... One's that send the spell back to the caster, so if you get jinxed the person jinxing you would get hit with their own spell." Alani suggested, Fred thought about it. "That's actually very smart, and it would work well with the Shield hats and Shield cloaks..." he mumbled. "I mean, the cloaks wouldn't help much against the Unforgivable Curses, but for minor to moderate hexes or jinxes they'd work... Moving on, me and George thought we'd get into the whole area of Defense Against the Dark Arts, because it's such a money spinner." Fred continued on enthusiastically. "This is cool.
