The Frozen Hearth

The icy mountain shelf that towers over Arxios in the north is a mystery for all who look upon it. The Hearth bars the ancient path that Stopstalk settlers supposedly traveled to come to Arxios at the beginning of the Current Era. It is unknowably tall, impenetrable, and attempts to circumvent the barrier with magic or technology have universally failed.
The glaciers at the mountain peaks are said to have pushed their way into the material plane from Cania, the icy wasteland layer of hell. For the aura of frost that they emanate has locked the surrounding mountains, and civilizations within, in a perpetual winter for thousands of years; A crushing twilight resemblant to hell's undending torture.
~ Excerpt from "Unexplained and Extraplanar Phenomena" by Derelinnt Toot, Scribe of the Delphi Athenaeum

The Cold Road Less a road than a well-trodden path, the Cold Road winds its way through the lower hills of the Frozen Hearth, and up into the mountains beyond. It is a place rather separate from the rest of Arxios, its people

Geography

The Frozen Hearth is a series of massive mountain ranges capped with immense glaciers. Very little of it is traversible even with proper equipment. Crushing blizzards, howling winds, and the thin air at high altitude make for an extreme environment suited to only the most resilient of creatures.

Climate

In addition to regular mundane cold, the glaciers of the Frozen Hearth seem to emanate an aura of unearthly cold that shrouds the surrounding region in an endless winter. The storm clouds never clear, and the snow rarely stops.
