The comprehensive guide to the multiverse

Description
The comprehensive guide to the multiverse was a journal created by an unknown entity, the first out-of-code character, in which they chronicled their exploration throughout the entire multiverse.

The journal, if real, contains information on every Anti-void, universe, and timeline, within the multiverse, and as such there have been many who have sought after it in the hopes of obtaining full control of all existence

To this day it has never been found, and it is unknown if it has ever existed.
