Built by Siegfried McCloud back in the times of before the Last War, the Astral Forge is powered by magma from the core of the planet mixed with the remaining magic of Viras the Netherlord.
Only those who heed its call may enter the heart of the forge, for they feel no heat from it's cauldron. No one knows what happens when inside, but those who are worthy return with the tools needed to continue their journey which are forever bonded to their soul.
