Tanya Markarov is a character appearing in Quest for Glory: Shadows of Darkness. She was initially the daughter of the innkeeper Yuri Markarov and his wife Bella, living with her parents at Hotel Mordavia, but was later charmed and abducted by Katrina. She then turns Tanya into a vampire like herself, to be her daughter forever.
The Hero finds Tanya inside Castle Borgov, in her room with Toby, her best friend who is also very large furry monster. The Domovoi in the Hotel Mordavia compels the Hero to save her, and eventually the Hero claims Erana's Staff. Toby sacrifices himself in order for the Hero to cast the Destiny Spell with the staff, essentially resurrecting Tanya and returning her to her parents.
