She was Embraced by Lerterimas, a childe of Malkav, in Finland during the first century. Louhi is a secretive vampire, with few recorded mentions throughout Cainite history. She is known to have once forced the Gangrel methuselah Ikkenai into torpor.
Louhi serves as the direct agent of an Antediluvian – but the ancient she serves is not Malkav, as one would expect of her clan. Instead her master is the Lasombra Antediluvian, and in his service she seeks to work a mystic ritual that will enshroud the world in eternal night.
Louhi's appearance is that of an old witch, with the smell of several alchemical experiments and she always carries a black staff inscribed with various runes. Her thaumaturgical powers rival even those of the most powerful Tremere elders.
In one scenario of Gehenna, she succeeds in this endeavor, if only temporarily.
Louhi is a queen witch in Finnish mythology and the mythology of Lapland.
