Guardian of the lost

”The Guardian of the lost” or just ”Guardian” is something that wanders around the cursed middle, always as if it is looking for something, but it never seems to find it. It is said to have been built by the Oldfolk to guard their cities, but since their passing, they have become hostile and uncontrollable, attacking everything it meets.
The guardian is a tall, dark stone figure with one, white glowing eye. It’s body is cover in old runes, that no one can translate
