Borgan loses her people. They were eradicated.
That kind of sadness, how could Azief understand it? He could not and he doesn't pretend to.
It does not excuse for what they had done, but Borgan…..sadness for her people have basis. So, Azief could only sigh at this.
In the past, he would not have cared this much. But he had seen many things. And while he did not empathize that heavily, he could understand loneliness.
And how lonely would Borgan be when she found out that she have no one else in this large Universe?
If she did not know, her existence might not be so tragic. But because she knows, it becomes tragic.
She is not talking to Azief, It is like she is recalling everything about her own past. Clearly, she look at these memories fondly.
Azief is confused seeing this Borgan. One of the things he does when he sees Borgan in this space is to determine what is she?
