Wailers

Wailers were the raiding ships of The Boneyard, made from the skeletons of Cachalots. These normally peaceful creatures were lured to Sirenstone, then savagely butchered, stripped to the bone, and repurposed to serve as the fleet of Nave, the Queen of Corpses. So called because of the sound of the wind whistling between the ribs, Wailers were accompanied by a telltale eerie fog, masking their movements, and allowing them to sneak up on most unsuspecting vessels and coastal settlements.

The purpose of the Dread Fleet is twofold. Firstly, to frustrate the Boneyard's enemies, especially Elhambra, and prevent their expansion. Secondly, and more importantly, assaulting passing ships and raiding communities allowed the Wailers to collect both the corpses of the vanquished and living slaves, dragging them back to the Boneyard. These constituted an endless supply of recruits for both the largely undead armies of the Bonelords, and the workforce dedicated to building the Vertebridge.
