"Tower of Mice" quest in The Witcher 3.
The tortured spirit of a girl who was eaten alive by rats at the top of a haunted tower politely asks you to take her skeletal remains and deliver them to the lover who abandoned her at the first convenient place right off the shores of the horribly cursed island to which she is bound (and to which she is inconsistent about whether her spirit is bound to the tower, or the island as a whole).
If you somehow manage to oversee the dozen or so red flags about that task and mindlessly carry out her requests, well... the region of Velen won't be too terribly pleased with what happens immediately afterwords.
