The plot is really weak so don't think much about that. It's actually just a straight line "Race for power" and the villains never get really any time to develop outside "They want power too and always beat you to it because they are better." Dallis is really a total BS with everything slapped on her to make her feel impactful but all she does is angrily scream every time she's on your screen.
This is why so many characters have to suffer for it because if the plot is weak, so are their characters. You pretty much just play it for the companions and that's probably why Fane feels like a main character to you. Each character (well, except for one) pretty much affect the fate of the entire race in general. Fane is just most obvious cause there's a very limited about of Eternal.
