Caidove

Background
Caidove was a mother who lived in Waterdeep, and was part of The Lost Tides, an adventuring party who were known for causing trouble but ultimatley being good people throughout the city.

There adventures eventually led them to Ravenloft, where Caidove at one point found some items of clothing of her children. It was never revealed what had happened to them.

Caidove was eventually revealed to have been transforming into a vampire the entire time she traveled with The Lost Tides, but took a potion to stop her transformation. She eventually turned after being captured by Lord Strahd, and ended up tricking Isolde into bringing Mystic Obscura to her and Strahd, for a final showdown.

Interactions With Mystic Obscura
Caidove met and eventually integrated herself into Mystic Obscura as they traveled through Ravenloft. She gained there trust a little, and even helped them kill The Abbot, who had revived Eloithe and let Strahd take her.

However, Caidove tricked the group, and managed to deliver them to Strahd. The fight didn't go as planned, Mystic Obscura overpowering the pair with Caidove being defeated and forced to retreat in her mist form, leaving Strahd to die alone.

It was revealed by Esmerelda, that all Vampires that were Strahd's spawn would not become Master Vampires; this would include Caidove, upon her resurrection.

Caidove ambushed Adrie Ofandrus at her Trial within Last Light, pinning the elf to a tree and warning her that Strahd wasn't dead, because you can't kill death. Beating Adrie badly, Caidove looked set to kill her as her vampires and wolves ravaged The Druid's for Adrie's trial, when Rynnik Oldoak appeared, killing most of her warriors and forcing Caidove to retreat.

Trivia
Caidove was played by Avalon in a different series on Geek House's channel, that was ultimately cancelled due to production issues. Avalon ended up reprising the role, for Session 30 of Reactors and Realms. She was played by Joey in Session 38.
