Balefire Hearth is a Vampire Counts military support building in Total War: Warhammer. A balefire hearth is a larger structure than a mere brazier - a raging hellfire inferno contained in a large, unholy fire pit.
Background
The great hearths located in the main halls of the largest Sylvanian castles have belched out the black, green and acrid smoke of corruption for as long as the von Carsteins have ruled. Once built, the balefire within the heath blazes hot and sonorous, bathing the battlefield in acrid smoke. Soon, others were created, spreading Undeathly contagions across the suffering world.
