The "Great Mage Rebellion" has a good ring to it.

For ultimate tragedy levels Riot should wait until the Jarvan IV VgU where in his lore Jarvan III dies and Jarvan IV is ready to ascend the throne and begin the long work of reforming Demacia deep seated prejudices and give mages their rights at long last. That's when Sylas puts his plan to destroy the throne into motion and Jarvan has to put down a rebellion that he was about to avoid anyway.

That would be dope

I'm sorry, but you want a rebellion by the demographic that Demacia first rebelled against? [sg-lux-2]
