Dwarf Anvil of Doom on display at Warhammer World.
The Anvils of Doom are ancient devices forged with great skill by the Runesmiths of old in the bowels of the Thunder Mountain. Using the energy of the volcano’s heart, Kurgaz, the most skilled of the old ones, melted gromril to forge the anvils. As they cooled, Kurgaz beat the Rune of Sorcery onto each gleaming anvil.
