"Luna!" Celestia reeled in the air, dodging her sister's vicious lunge. "Please! Stop! It doesn't have to come to this! Call back your soldiers! Return to Canterlot! I will forgive you!"

"You cannot undo all you've done, Sister!" Luna cried, winging backwards to gain height on Celestia.

"You will never be a leader," the elder alicorn said sadly, feeling the need to weep. It saddened her further to realize she could not.

Luna snarled. "And you will never be a god!"

Torn asunder by dissent and mistrust, Equestria is divided between the Sisters. One promises equality in magic and caste. The other maintains her rule is stable and just.

The future hinges on a single battle.

And neither Sister wishes to cede the sky.
