My main characters and their flaws are these:
Kyrriki Ednin -- The Lord of Ednin is petrified by fear of losing everything, a fear exacerbated by the murder of his sister and her husband. He has to overcome the fear so that he can make decisions that will protect his people. This means that he has to accept that he is the best champion they have, and that hiding is no longer the proper method to achieve his goals.
Gellayna Hehriya -- Gellayna Hehriya takes great pride in her peoples' traditions, but blind adherence prevents adaptability to her circumstances. She pretends to adapt, because acting is part of the job she was trained for, but must actually accept the world she has found herself in and its dangers in order to affect change. she needs to let her experiences in the empire change her...into something more than a Rextian born in Kordic.
Teshen Hehriya -- Is a bit overconfident in his own abilities and knowledge, a touch narcissistic, and resents Kordic rule of his people so much so that even when he becomes aware that his sister is likely in danger due to his actions, he embroils himself in more intrigue in the hopes of combating oppression, rather than seeking her out.
I think that will work. The basic conflict in the WIP is the xenophobia of the Imperial laws, and how one enemy seeks to use those laws as a bid for power while the Empire hovers on the edge of war with lands to the south. Fear and effectively, racism, are modes of control of an elite over an ethnically diverse Empire that wants to pretend it is homogeneous. Meanwhile, the diverse identities end up expressed politically, philosophically, and begin to unite and polarize the Empire after the death of the Lord of Rijnic and his wife (Kyr's sister), an act whose significance will bring war.
I'm afraid my academic background is firmly visible in this plot, but so be it. I'm working on actually reducing the description to something that does not wield such...highfalutin...word choice, but no guarantees.
