I actually met a man who could dual wield scottish claymores...for aboiut a minute, slowly and awkwardly. And he was 7 feet tall and built like an ogre. FYI though, you can use a hand-and-a-half sword in one hand, although a longsword would be better.
Jessyn will fight with a staff and unpleasant potions, with a single light longsword for emergencies.
