Wærhag (sometimes Wærxæg or Kurdalægon in some variants) was the smith-god of the Nart corpus, the divine forger of the magical weapons that the great Nart heroes wielded. He worked at his anvil in a celestial smithy — sometimes located in the heavens, sometimes in the underworld, sometimes at the bottom of the sea — and from his forge came the swords, spears, axes, and armor that gave the Narts their supernatural prowess in battle.
His most famous works were the weapons of the great heroes: the steel sword of Batraz (treated below), tempered to indestructibility in the magical waters of the cosmic sea; the bow of Soslan, made of star-iron and capable of striking targets that no mortal weapon could reach; the arrows of Sosryko, fletched with feathers from the wings of supernatural birds. Each of these weapons had a story of its forging in the Nart corpus, and Wærhag was the central figure of these forging-narratives — the master smith whose craft produced the implements of heroic action.
He had the typical features of the Indo-European smith-god: lameness (a feature shared with the Greek Hephaestus, the Norse Wayland, the Roman Vulcan), exceptional craftsmanship, isolation from ordinary divine society, and the working of magical forge-metals. The lameness has been variously interpreted in comparative mythology — as a sign of the smith's chthonic association (a sky-god lacks no limb; a chthonic god has marks of his earthly origin); as a sign of the smith's dependence on the forge-fire (which lames those who work it); as a symbolic mark of the craft-isolation that the smith requires.
Wærhag's cult survived in Ossetian folk-religion as the patron of smiths and metalworkers. The smithy-rites — the rituals performed when a new forge was lit, when a particularly important weapon was being made, when a smith took on an apprentice — were under his patronage, with offerings of bread and wine made at the forge. The cult was extinguished as a public religious institution by the Soviet-era industrialization of the Caucasus (which transformed the artisanal smith into the industrial worker), but elements survived in the modern ethnographic record and in the literary preservation of the Nart corpus.
