Sulan was a Jedi Master of the Nautolan species, and a male, who was a member of the Jedi Order during the era encompassing both the Cold War and the renewed war between the Galactic Republic and the resurgent Sith Empire. He tried to establish connections with akk dogs using Force-bonding techniques, however, these efforts ceased when an akk dog killed Sulan's Padawan. While stationed on Taris, he took on the task of training a Force-sensitive sub-species of Rakghouls, called the Nekghouls, in the principles of the light side.
Upon defeating Sulan in battle, the player(s) are presented with a choice of two distinct paths:
- Choosing the dark side path means overloading the reactor, which results in the death of all the nekghouls, after which the player then executes Sulan.
- Opting for the light side path means sparing the nekghouls, persuading them to reject Sulan's teachings and instead adopt the dark side. Subsequently, they will turn against Sulan and execute him.
