The Abyssal Forge is a living machine designed to harness the unfocussed dark power of the Abyss and create the most powerful legendary weapons. The Maker who built this abomination, known only as the Mad Smith, was shunned by his own people and sealed away in the Shadow Lands with his creation. However, the forge hasn't remained dormant all those years of captivity; it has constructed a vast army and now threatens all creation.
