Norvos is one of the nine Free Cities. It lies in the interior of Essos, between Pentos and Qohor.
Norvos sits among the Hills of Norvos, on the Noyne, a tributary of the massive River Rhoyne. Located between Pentos and Qohor, it serves as a gateway for caravans and travelers going east-west on the ancient Valyrian roads, with the ruins of Ghoyan Drohe to the southwest and Qohor to the southeast.
It is a land of rolling hills and terraced farms, surrounded by small walled villages that support the larger city. 
Norvos is ruled by a High Magister and a council of religious protectors.
The city is divided into two sections, with the High City on the tallest hill in the region, and the Low City located at the base of the hill by the river. 
There are three bells throughout the city, each given its own name,
- Noom having a deep sound
- Narrah having a strong sound
- Nyel having a higher pitched sound.
Bears are known to be made to dance down the Sinner's Steps.
Norvos is home to an order of militant Bearded Priests, marked by axe shaped brands on their chests. Like in other Free Cities the priests take unwanted young boys to be raised into the order.
Norvoshi men wear their mustaches long, with many sweeping them up into points and dyeing them. Norvoshi are known as masters at creating intricate textiles, including fine tapestries that are renowned the world over, and for an annual festival that features bears dancing down a path known as the Sinner’s Steps.
A Feast for Crows
As punishment for his part in the conspiracy to crown Myrcella Baratheon, Ser Andrey Dalt is sent to serve Lady Mellario for three years in Norvos.
