At the lowest reaches of the Grand Scar exists the Darkfall Abyss, a dark crag where only the impossible exists. The mythological monster in Darkfall Abyss is the Impossible. It is best if even the strongest parties run from the Impossible. Defeating the Impossible is improbable unless through something as powerful as the Wish spell. Through a small stream of water trickles to a path leading down. Down. Down.
Through the Darkfall Abyss lies The World Core. The center of power for the planet and the generator of heat for the realms. Currently the defeated remains of Lavos lie here, continuing to absorb energy and consume the planet. The Lavos Remains must be destroyed if this planet aims to survive or improve. Even in its corpse-like state Lavos Remains are formidably powerful and will take more than a torch and some fuel to destroy them. Destroying the Lavos Remains will drop the Lavos Core, a powerful engine component.
