The Crone of Cader Idris

Mallt-y-Nos, or Matilda of the Night, inhabits the cursed Welsh mountain Cader Idris, feasting on the unfortunate, unsuspecting souls who camp there. When a young man Morgan, haunted by demons of his own, stumbles into Matilda's domain, she must prey on his past to lure him to his death before he slips through her gnarled fingers and passes the boundary of her personal purgatory on the mountain.
