Aisling is blaming Kahina for the instability(Emperor's Dawn). That's a nice way of getting the attention away from her self.
The people backing Aisling and Emperor's Dawn are probably working to get Harry on the throne. They arranged the fake assassination attempt on Pat and framed Kahina.
As long as Aisling is able to steer Pat by his pants, he can be quite useful to them.
If anyone in the Empire is going to support Kahina, it will be Arisssa. She has everything to lose by giving the 'Traditionalists' a victory. If they gain momentum, they may be able to reverse the Lavigny family coup of the throne.
Open questions:
- Is Pat a naive as he seems, or does he just play along?
- What is Trovald's position? She is obviously to smart to give anything away, but I have a feeling she knows everything. She is a traditionalist, but she also dislikes Aisling and probably Harry as well.
