Melanie de Rolo

 was a member of the de Rolo family and the lady of Whitestone. She was responsible for the creation of the gardens at Whitestone Castle until she was suspected of necromancy.

Background
Lady Melanie was part of the third generation of de Rolos to be born in Whitestone. She created the back gardens of Whitestone Castle, where she grew poisonous plants from Wildemount with which she planned to murder her husband. She was eventually removed from her position for suspected witchcraft and raising of the undead.

Legacy
The gardens which were reconstructed after the Briarwoods' occupation to include some rose gardens, a small hedge maze, and a pond, as well as a revival of the walled poison garden by Percival de Rolo and Keyleth, who named it the Widow's Garden. Percival's youngest daughter, Gwendolyn Zahra Melanie von Musel de Rolo, was presumably given her middle name in honour of Melanie.
