|Darth Plagueis's scientific journal|
A scientific journal was composed by the Muun Dark Lord of the Sith Darth Plagueis at some point after he devoted himself exclusively to the study of the Force. The Sith Lord wrote down many of his own beliefs and theories, mainly regarding midi-chlorian manipulation and the means to achieve immortality.
The manuscript contained several sheets detailing Darth Plagueis's scientific approach of the Force, as well as notes on his theoretical and experimental work on midi-chlorian manipulation.
The journal included the following sections:
- "The Science of Creating Life"
- "Influencing the Midi-Chlorians"
- "Perpetual Life"
- "Concentrating the Force"
- "The Philosophy of Life"
- "New Explorations of the Force"
- "Transcending Death"
- "The Netherworld and Chaos"
- "Sith Spirits"
- "The Prophecy of the Chosen One"
- "The Culmination of the Sith'ari."
After Plagueis's death in 32 BBY, Darth Sidious took possession of his master's journal and integrated it into his Book of Sith, placing his own notes in the margins. After Sidious died on Onderon in 11 ABY, Jedi Master Luke Skywalker acquired the book, recording, in turn, his own notes.
