I understand that echoes and disturbances occur in the Force when many deaths take place at once or due to mass destruction. But these echoes could be created by Nihilius and the other Sith who were capable of mass destruction. What I don't understand is why Kreia couldn't achieve what she wanted WITHOUT the Exile?
Also I found this bit on Wookiepedia:
Traya then returned to Malachor V, where she intended to sacrifice herself to open up the larger wound in the Force in order to destroy it
What does the above line mean?
Also there is a cut scene in which Kreia expresses her disgust for machines and electrocutes T3-M4. What is the significance of this scene in the story
Another thing which comes in my mind is, how did Kreia and T3-M4 reunite and take possession of the Ebon Hawk in the first place?
