What is the name of Elden Ring’s spectral capital located above the Siofra River?

Nokron, Eternal City is Elden Ring’s spectral capital located above the Siofra River.

Nokron becomes accessible after the defeat of Starscourge Radahn. His gravitational magic had held back the stars, and his death causes a meteor to strike Limgrave, opening a massive crater near Fort Haight. The resulting path leads into the buried city.

The area contains the Mimic Tear boss, Night’s Sacred Ground, and the Fingerslayer Blade that advances Ranni’s quest. Nokron’s architecture and silver inhabitants reflect the history of an underground civilization that opposed the Greater Will and sought a Lord of Night.

Nokron is often confused with Nokstella, Eternal City. Both are underground Eternal Cities, but Nokstella lies in the northern Ainsel River region and is associated with Ranni’s later quest route. Nokron is the city reached through the crater created after Radahn’s defeat.
