Patrina Velikovna

Patrina Velikovna is a Groaning Spirit or spectre (depending on the version used) who resides in the crypts of Castle Ravenloft. Her tomb is labelled "Bride," so it is likely that she was a bride of Strahd von Zarovich, and hence most likely a reincarnation of Tatyana.

In Curse of Strahd

Patrina Velikovna was a dusk elf who learned much dark magic and is so doing formed a tight bond with Strahd. She asked for them to make their dark vows in marriage. Before Strahd could fully drain her life away and turn into a vampire, her elf clan stoned her to death. Strahd demands her body and put her in the crypts. Patrina's spirit restlessly haunts her tomb as a banshee, unable to rest until she becomes married. If raised from the dead, she is the equivalent of an Archmage NPC Archetype of Neutral Evil alignment, though she has no spells prepared. Once alive, she pretends to be helpful in wanting Strahd's destruction, but this is just a ruse to manipulate the player characters to her own ends.
