Mirt "The Moneylender" is a retired adventurer and noble of Waterdeep. He is friends with Durnan and also appears to be a high ranking member of The Harpers. He is also a Masked Lord of Waterdeep. A jovial, loud, boisterous man, Mirt loves to throw parties at his manor or talk of his past adventures. He often comments on his not being "much of a man of magic" but he's seen and used his share of the stuff, and has quite a collection of artifacts in his home.
Several years ago, Mirt was key in negotiating a peace between the elves of the Ardeep forest and Velrosa Nandar of Nightstone. He also maintains a hunting lodge ( Mirt's Hunting Lodge ) in the Ardeep Forest.
He is currently watching over Ander Blackwood and Maran Blackwood after the death of their mother, Westra (née Rommel) Blackwood. In a past fling, Mirt and Westra had a son, Bran Blackwood.
