"No," Celestia said sternly, placing her hoof on Luna's desk with a resounding thump. Luna jumped, blinking up at her sister. "Luna, it is not as it was a thousand years ago. We have been friends with the griffons for many centuries. We cannot think in such ways anymore," Celestia said before her gaze softened. "I don't... want to see another war if I don't have to. Especially not over a misunderstanding. Not after last time..." Celestia graceful features bore a pained expression that passed quickly. Luna remained quiet as she studied her elder's face. "If we did as you suggested and tried to encourage instability amongst the griffons to avoid them uniting in fear against us for something we did not do, and we were caught, we would only embroil ourselves in a more disastrous war."
