The Great Ocean

A boundless blue abyss where empires rise on tides of salt and the sea claims all.

The Great Ocean is the vast, treacherous expanse of water that separates the continent of Ulthuan from the mainland of the Old World and the southern lands of Araby. In the Warhammer Total War campaigns, it serves as a formidable natural barrier, a highway for naval powers, and a graveyard for the unwary. While often depicted simply as blue space on the campaign map, lore dictates it is a domain teeming with leviathans, cursed currents, and the lurking shadows of Chaos sea monsters.

Lore & Background

However, to the forces of Chaos and the pirate lords of the Old World, the sea is a hunting ground. It is said that the waters near Ulthuan are thick with the magical residue of the island's defenses, causing storms that can tear galleons apart in moments. Deep within its trenches dwell ancient horrors awakened by the whispers of Tzeentch and Nurgle, waiting to drag ships down into eternal darkness. The ocean does not merely separate lands; it actively tests the worthiness of those who sail upon it.

In Their Own Story

Captain Varrick gripped the wheel as the fog rolled in, thick and unnatural against the hull of his galleon. The crew was silent, eyes wide with a superstitious dread that no amount of coin could buy. Below the surface, something massive shifted, displacing water with a sound like tearing stone. 'The Elves say the sea protects them,' Varrick whispered to himself, watching a shadow rise from the depths, larger than any ship he had ever commanded. 'But I think it just wants to eat us.'

Reader's Guide

In Total War campaigns, the Great Ocean dictates naval strategy more than land borders do. It acts as a choke point for factions like the High Elves and Vampire Coast, who rely on superior fleet mobility to project power across continents. Settlements located on coastal provinces often provide bonuses to navy recruitment or trade income, making control of key ports essential. The ocean itself is not just empty space; it contains hidden regions where sea monsters spawn, acting as neutral threats that can ambush fleets regardless of faction affiliation. Terrain effects are critical here: storms and rough seas can damage ships during movement, while calm waters allow for faster travel. Factions with strong naval tech trees can dominate the map by cutting off enemy trade routes and launching amphibious invasions on isolated islands like Ulthuan or the southern archipelagos.
