An undead-type monster that wanders the frigid mountains. Bleakborn were once human women who got lost in the cold wilderness of the mountains and perished. The bodies of these women are preserved by frost and filled with demonic energy, keeping them in a kind of slumber and slowing their decay. Once a Bleakborn detects the body heat of a human male they will immediately reanimated and they will actively seek it, their body will also leak demonic energy which will cause the air around to grow cold, inadvertently trigger release of his spirit energy Their intended target will enter a state of high arousal which will make the man want to share his warmth with her. Finally when they are within range they will pounce their man to the ground and begin to copulate with him engulfing a man's penis within her and taking in his semen and spirit energy.
Even after copulating with a man in this way, once she has known the warmth of a man she will want to keep him as a husband, forever sharing his warmth as well as his spirit energy.
A Bleakborn does not limit themselves to just human males, they are also known to attack human females, trapping them in a cold embrace through sexual intercourse and filling them with demonic energy in this way also causes the female to become a Bleakborn like them, constantly seeking the warmth of human men.
(The idea for this monster came from the 3e Dungeons and Dragons book 'Libris Mortis' the book of the undead. It was also cold today in my area so I figured it was fitting.)
