Andchan has a great idea with Dracula, I love that idea.
Off the top of my head, a few myth alternatives I could think of are (in no particular order):
- Little Brother and Little Sister (Possible Triggers: Implied child abuse, murder of the heroine, spousal deception) A brother and sister escape their evil step mother, who curses the brother. The sister soon marries a king, but is murdered by the stepmother and replaced by her stepsister. The ghost of the heroine exposes the crime.
- The Three Princes of Whiteland (Possible Triggers: Abuse) Through a series of events, including fish-adoption and being beaten by trolls, a husband thinks he knows better than his wife. He tricks three princes into giving him clothing of invisibility to return home.
- Kalunga (Possible Triggers: Death) An Angolan chief refuses his people to eat or drink until his wife is brought back to life. The medicine man tasked to bring her back from the underworld discovers such a thing is possible, but also sees the chief will instead be reunited with his soon.
- Chase of the Severed Head (Possible Triggers: Infidelity, cannibalism) This is quite dark. A father tricks his children into committing an unspeakable crime. They find their revenge with the assistance of magic and bears.
- Princess Kaguya (Possible Triggers: None) An adopted farmer's daughter makes five suitors compete for her love before she escapes to live on the moon.
Of course, give me two minutes and I'll keep thinking and adding more as well. It is best I stop now.
