Esvele Rosznar

Lady Esvele Rosznar is a drow noblewoman from the City of Goldmask, part of the House Rosznar.

She met the party in The Yawning Portal. Here she told them that her brother Kressando Rosznar, ventured into Undermountain and hired them to return him to the surface "before he does something stupid". As an advance payment for this, she sponsored the party for 500gp for their journey into Undermountain.
