The Nentir Vale
Gendar is the proprietor of Gendar’s Curios and Relics in the Seven Pillared Hall (area #15). He trades primarily in antiques and relics of artistic and / or cultural significance, but also has interest in (and an apparent stock of) magical items of various sorts.
He is a businessman, and gets very short with those who do not follow through on their bargains. He can, however, actually be friendly (for a drow) with those who are reliably profitable for him.
