The Menhir are tall, rectangular-prism shaped stones, that appear to grow with time. They roam around the Plain of Fear, but are rarely seen in motion. They are creations of Old Father Tree, a god that created the entire Plain of Fear with his dreams.
They are intelligent beings that are often used as a medium for communication between Old Father Tree and those on the Plain. When the soldiers of the White Rose shelter in the Plain of Fear, the menhir often warn them of dangers to themselves and maintain a tentative alliance. They do not often provide complex or complete information, but are capable of it.
When a Menhir falls on its side it loses its intelligence and mobility, and will be found upright and silent shortly after.
