Clash of Diana and the Solari

Ever since Diana came out, I've wondered where Riot was going to take her and her story.

She exists as the only (known) antithesis to the Solari people, the only moon worshipper. If the Solari were distressed enough by her alternative thinking to schedule an execution, why haven't they dispatched an assassin or a garrison of troops to kill her. If there's anything a religion refuses to tolerate, it's competition. So I feel they should be hunting her, trying to disable any attempt for a competing religion/way of life to take hold. Likewise, why hasn't Diana become a preacher of sorts? I know she's vengeful and wants to witness the fall of the Solari, so why hasn't she accumulated a massive following and marched them to the gates with rage in their hearts? She should link with Elise and her followers, and seek to usher in an era of eternal darkness, where the moon reigns supreme and Elise and her spiders rule the night and feast on the captive Solari.

This war would provide SEVERAL opportunities for new champs, new game modes, new skins, new map? (Mt. Targon anyone) Could you imagine Celestial Elise? drools or a Fallen Leona/Pantheon more drool

Expanding on Mt. Targon, we don't know ANYTHING about it, or about the hidden temple where Diana found her suit/crescent sword and the people who built it/worshipped in it. Were there once two separate people? the Solari and this unknown moon-based group? Were they always enemies or did their relationship sour?

Additionally, Diana could request the aid of Noxus and bring yet another territory into their grasp. This in turn would attract Demacia and provide more conflict for the warring nations. (ALSO MORE SKINS)

Just an idea, would LOVE to see it happen though. Diana is so obscure. Fix it Riot <3
