The mountain widow is a spider that lives in the snowy mountains of Acherion. It is well adapted to the climate, as it burrows into the snow and stays underground until it is disturbed by the vibrations of footsteps. While underground, mountain widows will enter a meditative state of extreme focus where they listen to the vibrations of the mountain to "see" what creatures are moving where. For fun, they make thick webs in inactive volcanoes and calderas. When ignored, mountain widow webs typically last for centuries before erosion wears them down, often connecting multiple mountain ranges as groups of mountain widows migrate together.
