The wintry city of Dyinglight stands at the headwaters of the Sarkora River, surrounded by marshes and sulfurous hot springs. Dyinglight was once a mystical center of Sarkorian religion, its great ring of idols honoring Pulura, the North Star and mistress of the Aurora Iobara. Today, it is the haunt of the johud, demonic giants who hunt the Crown of the World and clash with the warclans of the Realms of the Mammoth Lords. Facing the great emptiness of the western tundra between the two lands, the demons have shown little interest in pressing for westward expansion.
