Sir Obi Wan Kenobi
As a young man in the days of the Republic, Sir Obi Wan Kenobi was an agent for the Jedi League of Force Champions. He is intimately acquainted with the dark side of the force, as he spent nearly a decade undercover within the Sith Brotherhood, secretly trying to uncover the identity of the organization's Patriarch. His time on the dark side left permanent scars upon his soul and to this day he battles the temptation to indulge his darker emotions.
When his identity was compromised and he was forced to escape the Sith Brotherhood, Obi Wan returned to the Jedi League. Many years of service later, he was chosen to mentor a new agent to continue his undercover work: a young boy named Anakin, groomed by the League especially for this role. Obi Wan spent many years raising and training the boy, but when the time came for Anakin to infiltrate the Brotherhood he was overwhelmed and seduced by the power it offered him. He ultimately betrayed Obi Wan and the League, forcing Obi Wan to kill him. Whatever remained of Anakin after that battle became the creature known as Lord Vader.
Obi Wan has spent the last twenty years living as a hermit on Tatooine, hidden from the Empire, studying the secrets of the Force and keeping watch over a child he swore an oath to protect.
