A fat, wheezing old rogue widely (and correctly) believed to be one of the Lords of Waterdeep, Mirt the Moneylender made his fortune in Undermountain after a colorful career as a mercenary general. As Mirt the Merciless or the Old Wolf, Mirt made many enemies, particularly in skirmishes in Amn, Tethyr, and Calimshan. He also made a few good friends, notably the adventurer Durnan.
More than one foe underestimates Mirt's agility and stealth because they see only his public act as a roaring, tipsy braggart. However, only a stranger to Waterdeep underestimates Mirt's cunning and his shrewd judgments of people. These qualities have made him far richer as an investor in business ventures than he ever became as a hiresword or treasure-gathering adventurer.
Mirt is a Harper as well as a Lord of Waterdeep, and has a heart of gold under his boasting and love of horseplay and tavern brawling. He wants to leave Faerun better than he found it, and the long tales of his adventures would seem to indicate that he just might do so.
