Playing as The Drowned requires Curse of the Vampire Coast DLC.
The Drowned is a Vampire Coast faction introduced in Total War: Warhammer II, led by Cylostra Direfin. They are a mix of undead Bretonnian cavalry and undead pirates who make port on the coast between Lustria and Naggaroth, and raid the seas east of the New World.
Legend has it that the sea witch Cylostra Direfin was once the favourite court singer of the Bretonnian king. Sent on a voyage across the ocean to sing for the Phoenix King, they were hit by a fierce storm. The madame’s notes turned to screams of fury as the ship sank, and all onboard drowned. Decades later, a Bretonnian galleon of rotten wood and tattered sails can be seen navigating the seas even in the most savage of storms. It is The Lamprey, the ship of the vengeful spirit Madame Cylostra and her crew, the Drowned.
Legendary lord choices:
As Mistress of the Deep, Cylostra Direfin’s very presence increases the loyalty of new recruits while also reducing the upkeep and recruitment costs for Mournguls and Syreens faction-wide.
Cylostra Direfin's personal ship is called The Lamprey.
