|“||I became the Sidra, ancient and deep.||”|
The Sidra River, or simply known as the Sidra is a broad, winding river sparkling like deepest shappire that flows through Velaris and sank into the sea gulf of the city. The Sidra is loitered by ships with sails of varying shapes, making it navigable. Two Palaces are located on the southern side of the Sidra and another two on the northern. Amren's apartment has a view of the Sidra River.
Rhysand gives Feyre Archeron a tour of the city of Velaris. They walk through the various Palaces in the city, located close to the Sidra River. Feyre learns about the city and how it was protected from Amarantha's rule. She also learns the names of the various parts of the city, including the Sidra River.
During Hybern's attack on Velaris, Feyre manipulates the Sidra River and bends it to her will. Feyre was gifted the power of water manipulation from Tarquin, one of the seven lords who resurrected her into a High Fae. She uses this power to manipulate the Sidra and create wolves out of water.
