The trail through the foggy forest breaks wide toward the south and you see a hill covered with dead grass and cairns of black rock. West of the hill, the land, the woods, and the sky vanish behind a towering wall of fog.

The frozen lightning strikes the very center of the hill, which has been turned to glass. Evidence of the powerful ritual that must have taken place yesterday.
