Death wakes up in the Forge Lands, a world populated by the Makers, physically imposing beings who are the Architects of Creation. He learns that their world, and many others, has been overrun with Corruption, a dark force that has blocked off the Tree of Life and has taken over many of the Maker's constructs. The Makers had crafted a massive Guardian to combat the Corruption, but had to abandon it before finishing the task due to the surrounding threats. With the help of constructs and a Maker named Karn, Death eventually reaches the Guardian. However, upon activation, the Guardian is tainted by Corruption and goes on a rampage. Death battles the Guardian and destroys it, allowing it to be reassembled free of Corruption. The Guardian self-destructs in the grasp of the creature blocking the path to the Tree of Life, which allows Death to reach his goal. Upon reaching the entrance, however, Death is seized by Corruption and dragged into the Tree. There, Death is accosted by the shadowy form of Absalom, whose hatred lasted beyond his slaying at Death's hands and birthed the Corruption, enabling him to take his revenge on Creation.
