^No, our character is just like the normal ones, but has to make a sacrafice at the end.
Revan has assambled all the (Lightside) Jedi in the unknow regions. They fight a bitter war against the new Sith commandar, and former Revan apprentice 'The Exile.' You as new rookie will be mixed in this events, whether you want it or not. Will you choose Exile and obtain power? Will you choose Revan and choose peace?
The war is slowly destroying the Republic, and it needs to be ended. Then it goes epic ^^
LS: Defeat Exile, end the war, and die doing it.
DS: Kill Revan, and the last hope of the Republic. With your death, you made way for the terror of the Sith.
Just an example...
