Which faction do you choose in Heroes of Might and Magic?

And who is this Bastila? Or is it a guy?

Bastila is the main protagonist of KotOR 1 (or one of the main ones, if you played as a female character). A mega-Jedi who defeated Darth Revan even before the game began, then fought on the player's side—that is to say, Revan again—then switched to Malak's side (the main villain of KotOR 1), and further, depending on the player's actions, could or could not return to the light path. And also, she fell in love with Revan if he was a guy. In KotOR 1, Bastila is the only Jedi who possesses battle meditation; with its help, the entire Sith (and when winning her over to the light side—the entire Republic) fleet fought much better than usual.
