History
Archivus was an unknown being who operated as "Chronicler of the Multiverse" out of the World Pool within the Reality Stone. When Sleepwalker of Earth-616 entered the World Pool, he asked Archivus for information on getting to Soulworld. In response she handed him a copy of Infinity Wars #3 as Man-Thing Thang Thoom arrived and the pair were transported into the comic book.[1]
