Kyra

Myra's sister, and the reason Myra came to Barovia at all.

She did not die at Ironwake — she was taken, pulled through a threshold of mist by unseen hands, and Strahd arranged it. He sent Myra the letter afterwards knowing she would come looking.

Myra found the bookshop she and Kyra had run, and the Wish scroll hidden in a binding inside it, and used it to restore her. Kyra is back and beside her.

In session 26, on a full moon inside Castle Ravenloft, the transformed Myra slashed the Pendant of Nyss out of Kyra's hands.
