The Siren Queen has been monarch of the Sirens’ Sunken Kingdom since the days when the Ancients inhabited what is now the Sea of Thieves, and still despises all those who dwell on dry land. This enmity stems from the Ancients’ betrayal and capture of the Siren King.

Despite their hatred of humans, Sirens do find uses for them – ships that are dragged to the bottom of the sea become raw building materials to expand the Siren Queen’s domain, while captured crews can be sealed away and transformed into her obedient Ocean Crawlers.
