Yay, Aron finally has something to do! And by extension, Alair is more developed, hooray!
I know she's not the primary focus, but I really liked your characterization of Alair here. She doesn't get much in the game itself, other than trying to stop the fighting, and I like how she goes from the general interpretation of being calm and peaceful to nearly slicing off her brother's head (and rightfully so).
So much for Lune mellowing out in this timeline.
I guess this Kara is lucky she didn't turn out like the other Kara.
My only issue is that after the incident with Lune, Kara didn't say or do anything to convey that she was upset with Aron for any reason. Though I guess I can understand Aron's guilt at not being able to do more, Kara was getting pretty cozy with him afterwards, so the drama and tension between them (even if it was just from Aron's end) didn't feel entirely natural to me.
