The Blood Voyage is a minor Dark Elves faction introduced in Total War: Warhammer II. It is a special faction with a single army and spawns the turn after Crone Hellebron of Har Ganeth calls a Death Night. The army emerges from the city of Har Ganeth in Naggaroth and sails towards Ulthuan.
A new Blood Voyage is summoned after each Death Night. When the Blood Voyage is destroyed, Har Ganeth gets money from their plunder and murder. Units in Blood Voyages have Frenzy in battle, are fairly high tier (depends on Hellebron's level but is usually rather good) and the lord is unbreakable, but the army cannot replenish losses like a normal army.
The Blood Voyage is marked by a red storm cloud over the leader's unit.
When the Blood Voyage is defeated or disbanded, Har Ganeth (if you are playing as it) receives an amount of loot.
When playing as Avelorn, Blood Voyages may periodically spawn outside Ulthuan as a frequent enemy.
This faction cannot be interacted with.
