In Fair Barovia

By asking around various townspeople of Vallaki for a person matching the approximate appearance of "Henrik", the player characters can discover that Yelena was the last person the murder known as "Brother Henrik" (actually Leo Dilisnya) talked to before leaving town. She will tell them he went to the Monastery of the White Sun. Aresek remembers little of the encounter; Leo drank some of her blood and beguiled her. Delisnya's interest in her stems from his researching indicating she was a descendant of Strahd through an illegitimate offspring he had while alive through a tryst with a woman from the Olavnya Family. Drinking this blood affords Dilisnya protect form Strahd's detection.
