"This was like nothing I'd felt before. It was an animal, a creature of infinite fire that breathed with the stag's strength and the sea whip's wrath. It coursed through me, stealing my breath, breaking me up, dissolving my edges, until all I knew was light." — The fetter's impact on Alina's power, Siege and Storm

The sea whip's fetter is an amplifier that consists of the seven golden scales of Rusalye.

History

Siege and Storm

At the Darkling's behest, Malyen Oretsev tracks down the sea whip. After a violent exchange with the Darkling and his guards, Alina Starkov kills Rusalye with a single blow, and Tamar Kir-Bataar cuts seven scales from the beast for Alina to harness as a cuff-like amplifier that circles her wrists. Alina is immediately able to harness more light than before.

Ruin and Rising

After the final battle of the Fold, the fetter breaks apart into pieces.

Description

The scales that made up the fetter are edged in gold, unlike Rusalye's other scales. They fused in an overlapping row around Alina's wrist.
