Inn Harm's Way
Kasimir is the leader of the remaining Dusk Elves in the Vistani Camp outside Vallaki. He is around 500 years old and remembers a time before Strahd came in and killed all the female dusk elves as a punishment for his brides’ murder (this bride, Patrina, was Kasimir sister). Now the dusk elves cannot reproduce and continue their line, and when they’ve tried to breed with the Vistani, they were killed. Kasimir has suggested that there’s something in the Amber Temple to the south that might help bring his sister back – and might also help defeat Strahd.
He’s agreed to guide the party to the Amber Temple if they ever wish to undertake the expedition.
