User blog comment:GlassGolem/Overreaching Plot Idea: Light vs. Darkness/@comment-50.175.158.72-20140723033248

As much as I hate Light Vs Dark, Black vs White, I do think there needs to be an overarching bad guy, entity, group, thing. Something thats operating in the shadows while Ruby and company fights the fight.

Its partly the reason I think the last airbender was so great, no matter what Aang did, it was always part of a greater quest against an overarching evil.

There is the problem of the generic evil. Its extremly boring, people who are evil for the sake of being evil is overdone and really kills the mood. I would hope there will be some backstory for the reason why cinder and co does the things they do, and hopefully some revelations that makes you question whether the "Good side" is really the right one.
