Zillo Valla has temporarily frozen time in order to recruit Superman for her team of Multi-Versal Supermen she is forming to take on a dark threat. In return for his cooperation, Zillo offers Superman the Ultimate Prize - a substance known as Ultramenstruum (or "the Bleed"), a mystical world-nurturing fluid found within the Orrery of Worlds which only Monitors are able to capture or bottle. The Ultramenstruum, Zillo Valla claims, is capable of saving Lois's life. With only a short period of time before the time-stream thaws and Lois's heart gives its final beat, Superman agrees and returns with Zillo Valla to her ship.

Once aboard the Ultima Thule, Zillo and Superman find that the ship is being attacked by another much larger Universal vehicle which seems bent on destroying the Thule. Racing through the arteries of the Multiverse, the Ultima Thule plunges through different Earths (including Nix Uotan's gravestone universe, the empty Earth-51) before crash landing on a plane outside the Multi-Verse known only as Limbo.

Stepping outside the ship, the Super-Men are greeted by Merryman, who explains the welcomes them all to Limbo - the place where forgotten characters go to live out the rest of their pointless existence. Looking to escape Limbo before his memory and mind slips away like the rest of its inhabitants, Superman enquires about the Library of Limbo. Apparently there is but one book within the Library but no one is capable of reading it since it contains and infinite amount of text - every story ever told within the multiverse.

Superman decides that since the book contains every text ever written, it must also contain instructions for the Thule to re-build itself so that they can escape. With the Thule's infinite memory capacity, all they need to do is get the book into the Thule itself and they should be able to escape this place of emptiness.

While Superman and Captain Marvel of Earth-5 go into the Library to retrieve the book, Zillo Valla is explaining to Overman that the Thule's main source of energy is Zillo's life force - a life force which is draining by the minute. Overman, desperate to find his lost cousin (the Nazi Supergirl crashing from the skies in Final Crisis #3) willingly gives himself over to Zillo Valla who sucks out his life blood like a vampire so that she may survive.

Back within the Library of Limbo, Superman and Captain Marvel are absorbing the knowledge of the Infinite and watching the tale of the creation of the Orrery from the perspective of the Monitors. As the first Monitor, the over-being of all of existence experiences the events taking place in the Multiverse, the tales of heroics and villainy trickle down to the society of Monitors themselves. As they become infected by the 'germs' within the Orrery and all of their "stories" and lives, the Monitors begin to fear the structure which has come to symbolize the events of the Great Crisis - a gigantic Metal Superman Statue. The Monitors believe that the statue itself is somehow tied to their end-times and feel as though the Superman will save them from the dark shadow which grows over their existence. "Deep within the Sepulcher of Mandraakk there is a restless stirring..."

Before they can absorb anymore of the story, Captain Marvel loses grip and is sent flying backwards from the immense power of the book. Superman carries him back to the ship and recruits all of the residence of Limbo to help him bring the book back to the ship. He steps inside to find Zillo Valla standing over the body of Overman. Blood dripping from her vampire teeth she reveals that Mandrakk the Dark Monitor has awakened!

Just then, the immense ship from earlier, Mandrakk's eyes, have found the Ultima Thule. As the sky breaks open and fills with the crimson blood of the Ultramenstruum, Ultraman stands holding the Book of Infinite Texts. He looks at them and shouts, "I have the proof here in this book! Evil triumphs, Superman, and there's nothing you can do about it! EVIL WINS IN THE END!"
