Isolde

Background
Isolde was a halfing Cleric who was part of the adventuring party The Lost Tides. She was trapped in Ravenloft, and seemingly tortured by Lord Strahd, during her time there.

She eventually escaped Strahd, only to be experimented on by a fallen angel known as The Abbot. Her skin was taken, to make Strahd's new bride with, before she fled him as well.

Interactions With Mystic Obscura
Isolde was eventually able to escape from Ravenloft, by unknown powers, and travel to find Mystic Obscura. She informed them Lady Eloithe was there, and that it was possible for them to retrieve her. She also seemed to posses some knowledge regarding Arannis, stating Strahd was angry at him and had been looking for him. The group followed her to a crossroads, where they were engulfed in mists. Isolde said Caidove was waiting for them and that she wasn't going back, before heading off into the night.

Isolde was living in Neverwinter and writing to her family in Sunsway, when they were murdered by Hector, who was hunting Isolde for unknown reasons.
