Leannan Sith

A Leannan Sith is a beautiful fae creature in Gaelic lore that acts as a muse for her human lovers, there is a price however, the poets and artists she cavorts with are said to live short (but productive) lives and are sometimes driven to madness by their beauty.

Yeats popularized the notion that these beings where vampiric in nature and their lovers where victims who’s lives sustained the fairy creature.
