Celestia was one of the few ponies that could manage to be introspective while she was being attacked by her very special somepony.
“All is fair in love and war.” Her tormentor had said, using her magic to create more and more magical constructs with which she assaulted the sun goddess.
She had uttered pleas for mercy in between panting for breath and laughing her behind off. Only for another tendril of magic to form into what was sure to be Celestia’s downfall.
She supposed it was her own fault for teaching the ever resourceful Twilight a feather fall spell.
