Hm. Well. Probably at the hands of my wife's lead character, who after seventeen real years is not only the most powerful PC in the 40 years of my campaign but one of the world's most powerful wizards. In the biggest naval battle in the world's history, against the Armada of Badness, she saved the Good Guy Allied Fleet from destruction (some 400 ships worth) by witching up the Mother of All Windstorms and wafting them all to safety. (The elven emperor, with a dozen archmages, followed up with a mass smackdown on the aforementioned AoB.)
