The Ancient Order of the Whills ToJ

Lore (Rank 1) - The Order of the Whills is an ancient Force Tradition that has existed as long, if not longer than the Jedi. Unlike the Jedi, the Whills refrain from engaging in active involvement with Galactic affairs and devote themselves to scholarly pursuits almost exclusively. They have one of the most complete histories of the Galaxy known.
Lore (Rank 2) - The Order of the Whills has been largely supplanted by the Jedi, and have faded into obscurity. It is organized into two main bodies; the Shamans - who explore the mysteries of the Force, and Guardians - who act as protectors of their various shrines and temples.
Lore (Rank 2) - The Order of the Whills views the Force slightly differently than the Jedi. While both understand that the Force is generated by living beings, the Order of the Whills believes that an individual who calls upon the Force, is channeling the Force generated by those around them - and treats the Force as an infinite number of individual essences instead of a single effect. This has led to their saying of "May the Force of Others be with you."
Lore (Rank 3) - There is a subdivision of the Shamans of the Whills, known as the Keepers. They are responsible for ensuring that the History of the Galaxy is kept up to date and that their understanding of the past is expanded through research. Each Keeper maintains a Journal - a record of all the knowledge they have gained through their studies and each Journal is added to the collective knowledge of the Order upon the death of the Keeper.
