From The Regnum Animale by Bishop Vitellus of Oaken:
Outside of the concerns of land-dwellers, the Sea Kings of Leviathae are a varied lot. Almost all information that is known of them and their folk come from sailors, who are known for the outrageousness of their story-telling. Yet so troublesome was the raiding of ships by the self-proclaimed cetacean Corsairs of Leviathan and the coastal raids of the crustacean Blood-Red Tide that in both cases the High King was forced to rally his forces to bear arms against them. Even now the only folk who claim to have treaties with the Sea Kings are the guildmasters of Bulwarkeen. If this claim is true, it would go far to explain the success of their trading fleets where other ambitious souls have failed.
