The World Before Time is a world destroyed by Chaos. Its metallic core, known as Mallus, was hurled through the cosmos by its destruction, dragging the god Sigmar with it. It was caught up and placed in the firmament by the Great Drake Dracothion. Sigmar forged a necklace of sigmarite from the core of the old world for Dracothion in gratitude, and now Mallus hangs above Sigmaron, in the Realm of Azyr.[1a]
