Born and raised on Courasant to a father who was the Chief Financial Officer for the Republic. Ran slush funds for their dark ops and unspoken misdeeds. Dad (Brekken Bar Sinestre) ingratiated himself into the upper crust, but our cultural group was a lower caste and never allowed him to reach the top. When I started showing Force traits, I was then picked as a Jedi for the academy. Always carried a rebellious streak because I had seen the sausage being made. Species rank in Lightsaber. In Clone Wars, apprenticed to a Jedi Mace. Chosen for covert operations and infiltrations. Trained Prince Luke in Jedi Stealth.

When Order 66 occurs, I used my skills and connections to slip into the underworld. When Imperial Jedis are started, handpicked by Anakin to join. Becomes prominent IJ in Investigations. Eventually, Anakin pushes me to join the Order of Vader as a top assassin. Flees to avoid becoming a Darth and becoming a Sith. Sets up a plan to appear to have been abducted and possibly murdered because of prior underworld connections. Works for Grondle on Canto Bight. I have a legit cover story and persona, where I do enforcement of owed debts for Grondle the Hut. Think The Wolf from PULP FICTION. Worked for Grondle to "keep enemies close", know that he's Darth Haradda, a Sith Lord. During this time, changed my name to Flint Acharontis.

Leaves when the Guardian Stars blow up because he recognizes that he can take down the idiots who tried to turn him into a monster and potentially establish a more libertarian and meritocratic society: Less politics with fewer connections and more capability.

Motivation to become a Jedi: Appreciated the meritocracy, no discrimination.
Motivation to Leave Jedi's: Being forced to become an assassin for Anakin.
The motivation for joining the rebellion: Anarchy, baby. Meritocracy.

49 morality pure grey
