The Florid Sword was a mysterious swashbuckler and fang-fighter.
Later in the series, we discover that this mysterious man was in fact Gammon, a defiant leader of a rebellion in the Ice Prairies.
He adopts Maraly Weaver and she becomes Shadowblade, another feared defender of the streets of Dugtown.
“To be sure, Sneem, thou fiend, the Florid Sword hath run you through like unto a bolt of iron lightning piercing the watery depths of the Mighty Blapp, may she run wide and muddy all the days of mine own life! Flayed by my blade! Aha!”
