Celestia got a letter from princess twilight saying Ponyville was under attack. Twilight wast sure what was attacking so Celestia went to investigate and see if it had something to do with the keys of harmony. Luna wanted to be apart of it to but sadly, Celestia said to stay there in safety and look after Canterlot. Luna was sick of Celestia telling her to stay in the castle and protect Canterlot. Luna wanted a part in life to protect all of equestria just like Celestia. Luna was heart broken just thinking how usless she was all this time…

What do you think will happen to Luna?
