Edgar Yronwood

"When I was a boy of sixteen a great lord caught me with his mistress. He should have been honored, instead the fat old fool challenged me to a duel. Thanks to my age and status, only to first blood. But his mistress... and his wife, warned me which of my parts he intended to draw first blood from."
