The Lady of the Waves
The Lady of the Waves was one of the two ancient gods of the Three Sisters, a cluster of windswept islands in the Bite. Before the Andals came to Westeros, the Sistermen worshiped a pair of deities: the Lady of the Waves, who ruled the sea, and the Lord of the Skies, who ruled the wind and storms. According to Lord Godric Borrell, the Lord of Sweetsister, these gods "made storms every time they mated." The Lady of the Waves was thus a goddess of the sea's power and fertility, intimately tied to the harsh maritime life of the islanders.
Worship and Displacement
The Faith of the Seven, brought by the Andals, eventually supplanted the old gods of the Sisters. The septons forced an end to the practice of casting dwarfs into the sea as offerings to the gods, a custom Lord Godric recalls with a hint of regret. The old gods were not entirely forgotten, however. Lord Godric speaks of them with a fondness that suggests a lingering cultural memory, a remnant of a pre-Andal identity that the Sistermen have not fully surrendered.
Narrative Significance
The Lady of the Waves appears only in the recollections of Lord Godric Borrell during a conversation with Davos Seaworth. Godric uses the old gods to explain the storms that drove Davos to Sisterton, framing the weather as a sacred act of procreation rather than mere natural phenomenon. This invocation of the old gods serves to establish the unique, insular culture of the Sisters—a people who, even after centuries of Andal rule, still see the world through the lens of their ancient, elemental faith. The Lady of the Waves is a symbol of this stubborn, pre-Faith identity, a reminder that the Seven Kingdoms were not always united under the Seven.
