Grave hags - The Witcher 3

Cremation, now that's one thing men could learn from gnomes. Burying bodies out in the fields, why, it's like laying out a welcome mat for monsters! Best case scenario, some ghouls will sniff them out, eat their fill and be on their ghoulish way. But if, gods forbid, a grave hag takes to feeding at your cemetery, you'll have no end of trouble."
– Jacques de Villepin, Oxenfurt Academy

Few monsters' names fit as well as the grave hags'. As one might guess, these creatures resemble aged, deformed women and loiter near graveyards and battlefields. Grave hags feed on human corpses and in particular on the rotten marrow which they slurp from human bones using their long, prehensile tongues. Once a hag has devoured all corpses within reach, she turns to killing men and burying them in the cemetery as she waits for them to decompose.

Grave hags use their tongues in combat to grab or flog their victims. Claws built for digging up buried bodies serve just as well as weapons to rend flesh. Though clumsy in appearance, grave hags move and attack at great speed – sometimes even a witcher's reflexes are too slow to avoid their blows.

Grave hags are territorial creatures. Their lairs resemble caricatures of human homes and are built near burial sites. They venture out at night to hunt, stalking straggling travelers or mourners too lost in their grief to notice the setting of the sun. On rare occasions hunger-driven grave hags will hunt during the day. They are less dangerous at such times, for sunlight weakens them considerably.
