For the most part, yeah. Though we should discuss technological setting and what this event that gets attacked actually is. In the dream I had it was  this festival celebrating the anniversary of a peace treaty between many nations and the sort of....creation of what I’d probably call a commonwealth. But it doesn’t have to be that. Could be anything. 

Also are you thinking kinda sci-fi-ish? With either mod modern or semi futuristic tech? Or were you thinking something more medieval?
