Silver Surfer: Antibody

Galactus is dying, and his new herald, Nova, enlists the Surfer's aid to help save his life. Surfer and Galactus strike a deal. He would help Galactus if in return, Galactus gives him information about Zenn-La. Galactus agrees and allows the Surfer to enter his body in order to destroy the scourge that is killing him, while Nova remains on the outside, defending Galactus from attacking Wanderer ships. Surfer learns that Galactus knows nothing about Zenn-La's location because, in his anger, he hurled the planet so far away, even he knows not where it came to rest.
