The Wet Nurse is a single minded monster that serves the Entity of the Holy Lands. It's only purpose is to nourish the creatures born in the Holy Lands with the molten milk it produces. This is the nutrition that carries within it the imperatives and instincts to serve the Entity of the Holy Lands. The monsters birthed by the Mothers and Grand Mothers of the Holy Lands are taken by the Wet Nurses who's milk is the very will of the Entity. Humans taken from their mothers at birth are nursed by the Wet Nurses to create the mindless shambling masses of Holy Landers that live in the Entity's fiefdom.
