Though I sincerely doubt, with the threats they have in their world, that Celestia would have given Cadance the Crystal Empire if she had zero ability to protect its power or fight for what she loves. Just because someone is against fighting doesn’t mean they can’t. She may not be the warrior hero, but neither is she the classic damsel in distress.
At least, that’s the idea I’m going off of in my story, which is pretty much anything but sunshine and rainbows. Hints here and there, but, yeah… Dark, but thankfully not a tragedy.
I love pony armor. Pony armor is fun.
