The game The Witcher.
"No other monster inspires so many myths and fallacies as the alp. People believe that this vampire is able to turn into a black dog or a venomous toad. They mistake alps for succubi, believing them to be lecherous and inclined to seduce handsome young men. Folk tales describe their charm and their beautiful, seductive voices, as well as their loathing of virgins. What is true beyond any doubt is that they move noiselessly and attack by surprise, rarely giving their victims as much as a chance to scream in terror."
