The real history of the Solari and Lunari

My concept:

The Solari and the Lunari once served as the spiritual leaders of the Rakkor, in tandem. Where the Solari were forthright, unyielding, and strict in their doctrine, the Lunari were mystic, skepticle, and flexible. The Solari supported a structured social heirarchy, military elitism, and isolationism. The Lunari were less predictable, favoring diplomacy. Their council members were philosophers, more concerned with arcane signs and portents than the pursuit of the ultimate warriors.

Naturally, they were at odds. The Lunari's favor in Rakkor society had waned, and the Solari became the dominant authorities on spiritual matters. Then predictions were made by the Lunari, and harsh words spoken, it seemed to threaten the Solari's dominance of the Rakkor. People listened to the Lunari's sound council, that there should be much more to life than warfare and the crafting of weapons. The tides began to turn as doubts grew in the Targon people about the Solari leaders.

The Rakkor, in observance of their celestial faith, observed the Solstice, Equinox, and Eclipse as times of celebration. The Solari leaders began to collude with one another, fearing the coming Eclipse would be a boon to the Lunari and their following. They then staged a coup, saying the Lunari were planning their own coup during the Eclipse whne the Moon's power would be greatest, and rallied the fear of their own followers to cleanse Rakkor Society of all Lunari in a dawn massacre.

Thus, the Solari gained complete control, naming the Lunari as heretics and traitors.

I think the central theme should be that all the guidance received from any Sun or Moon spirit should be in favor of peace and harmony between the two. That they aren't really at war with one another, but two different halves of a whole. That way, the Solari's actions are simply misguided, and the Lunari are the crushed victims. Whenever the spirits speak up, it's not in opposition to the other, but a perceived battle that is now part of their cultural memory.
