Prologue: Doctor Who?
They called him the Doctor. "Doctor Who?" was a question that often followed. The name meant "healer" and "wise man." And he was a healer. And he was a very wise man, wiser perhaps than any Jedi who ever lived in the history of the Order itself. The Doctor's species, the reclusive Gallifreyans, were a species blessed with longevity, and while the Doctor looked like a young man in his late thirties, he was so old. So very, very old.
In his 900 years of life, the Doctor served as Grand Master of the Jedi Order for 500 of those years, the undisputed leader of the Order and head of the Jedi High Council. Over the many centuries of service that the Doctor had provided, he had trained countless Padawans to Knighthood, and he remembered all of their names. Every last one.
The Doctor served during the Clone Wars and the final days of the Galactic Republic, and he continued to operate in secret during the reign of the Empire, which was headed by the evil Darth Sidious. He was there when the Jedi Order fell to its knees at the hands of the Sith, and he was instrumental in the return of the Jedi and maintaining the Old Order's legacy alongside Luke Skywalker, Obi-Wan Kenobi, and Jennara Oswin.
This is the story of the Doctor during those days, those days when the fate of the balance of the Force itself depended upon his choice.
