Kareena is a sorceress who lives in a small hut in the woods. Philge, Baston, and an injured Freezo come upon her hut while lost. Despite their intrusion into her home and Freezo's negging, she offers to escort them to the gypsy village to get help from Madame Eva. She guides them through the woods, but is eventually revealed to be a minion of Strahd.
She tells the Dragon friends that she is both paleo and vegan, and that she and Madame Eva went to university together.
Kareena is a normal human woman and definitely not afraid of sunlight, nor does she possess any other vampire qualities because she is a perfectly normal human and definitely not a vampire.
