Siofra is the river that runs beneath the Lands Between, in a cavern so vast that its ceiling shows a perfect false sky of stars. Its valley belongs to the Eternal City of Nokron, one of the cities of the Numen long entombed beneath the earth on Maliketh's order. The Numen of Nokron worshipped the ancestor spirits, great-antlered stags whose breath is silver mist, whose Crucible-tinged forms the Erdtree's later gold did not permit above. To follow Siofra is to walk through a starlit night that has never seen a real sun.

Nokron itself is a city of black-and-silver towers, half intact, half overgrown with the spires of those who fled here after the Night of the Black Knives. The Mimic Tear that haunts its mausoleum was forged from the shape-eating silver tears of the city; the Fingerslayer Blade, the only weapon that can sever a Two Fingers from its spine, was hidden in a chest at the centre of Nokron's great library. Below Nokron lies Mohgwyn Palace, accessed only by the bloody portal Mohg tore open from within.

Remembrance of the Regal Ancestor Spirit, hewn into the Erdtree. Ancestral spirits exist as a phenomenon beyond the purview of the Erdtree. Life sprouts from death, as it does from birth. Such is the way of the living.

WeaponFingerslayer Blade

The hidden treasure of the Eternal City of Nokron; a blade said to have been born of a corpse. This blood-drenched fetish is proof of the high treason committed by the Eternal City and symbolizes its downfall. Cannot be wielded by those without a fate, but is said to be able to harm the Greater Will and its vassals.
