Yesterhill

''A great mound rises from the earth. At the top, a stone circle rings in what seems to be a great wood effigy. Just beyond it, a black tree reaches to the sky, great branches carving out segments of gray. A winding path works around the mound, past cairns and torches. The flickering shadows of marching guards can be made out in the uncertain torchlight.''

Yesterhill is a sacred site for the forest folk of Barovia. Back when Barovia was called Cernunnen and belonged to the Fanes, the forest folk walked freely, worshiping their ladies three, particularly The Huntress, a goddess of life and death cycles.

At the time the party arrived, the forest folk were conducting a ritual to appease Strahd and raise a strange, monstrous effigy. Led by Dervlekk'dda (now dead), the forest folk had been targeting the winery, for reasons unknown, as well as stolen the last of the Martikovs' three magical gemstones.

After their defeat and the destruction of their effigy, the remaining forest folk vanished into the woods, leaving behind subtle marks that Daphne recognized as way-marks, essentially druidic trail-blazes.

The Dark Grove A great tree, known as the Gulthias Tree, lurks in a grove at the top of the hill, just beyond the ritual circle. The inside of the tree had been filled with undead monsters, that suppressed the remnant of the Huntress that is normally bound to the tree. The Gulthias Tree has been cleared of undead, but still needs to be reconsecrated to return the Huntress' fane to her.
