The Journal of the Whills was a legendary record of events in the galaxy. Ostensibly, the Journal was maintained by the Ancient Order of the Whills, a mysterious group of beings.
During the Galactic Civil War, some individuals wished their efforts be recorded in the Journal of the Whills, indicating it was an on-going recording of the history, widely known as a tradition to the inhabitants of the Galaxy. The recording of their names and efforts in the Journal signaled their importance to the history, hence honorary.
The inclusion of a brief overview of the fall of the Galactic Republic and the rise of Palpatine's New Order in the Journal's First Saga established that the Journal’s beginning included at least the Clone Wars, though how far backwards or forwards in history the Journal’s first segment covered was unknown.
As well as not having a clear beginning, the style of the Journal is inconsistent. Whereas the First Saga is expository, written in the past tense with a third person perspective, another known excerpt, from early script drafts, is written in a formatted poetic style reminiscent of many religious texts. The excerpt reads as follows:
Although it has never been confirmed, it is possible that this excerpt deals with the Prophecy of the Chosen One seeing as that it does seem to make what could be considered references to Anakin Skywalker, though it could just as easily be referring to his son. The numeric reference is important as it indicates a possible chapter and verse from which the excerpt is taken. The style of the excerpt is also written in the future tense with a prophetic tone, a clear difference from the larger excerpt from the First Saga. However, the First Saga excerpt does indicate that some form of poetic style may be consistent throughout the Journal, as it states:
"The Old Republic was the Republic of legend, greater than distance or time. No need to note where it was or whence it came, only to know that... it was the Republic."
In his early drafts, George Lucas ostensibly planned to use the Journal of the Whills as a plot device to connect the Star Wars galaxy to our own. In Star Wars: The Annotated Screenplays, Lucas explains his original intent:
"Originally, I was trying to have the story be told by somebody else; there was somebody watching this whole story and recording it, somebody probably wiser than the mortal players in the actual events. I eventually dropped this idea, and the concept behind the Whills turned into the Force. But the Whills became part of this massive amount of notes, quotes, background information that I used for the scripts; the stories were actually taken from the 'Journal of the Whills'."
