Equestrian war

The book of wars

In twilight's castle Luna was taking care of Celestias wing, it had been damaged badly. Celestia let out a shaky breath as Luna began to stitch up the wound, luckily there was still some needle and thread from when rarity mad them costumes.

"Sister.....you have to go help.....the others"
Luna shook her head
"No sister I shall not leave you"
"I'll....be fine....but they won't"
Luna looked out the window to see Sunset shimmer and Twilight create a force field around them all as ponies hit it with their swords
"Sister, they are doing fine, if they are in need of help I will fly to their aid but for now you need my aid"
Luna continued stitching up the wound, she cut the string with her teeth and put the needle and thread down
"Well, how is it sister?"
Celestia opened her wing but quickly closes it
"Still.....hurts"
Luna sighed
"You need to stay in here and rest"
"I can't....they need me"
"Sister if you try to help them you will end up tearing your wing even more"
Celestia sighed
"Alright....I'll stay"
Luna nodded before leaving the castle to help the others.

Celestia watched as Luna used her magic as the ponies attacking the force field flew back dropping their swords and landing on the ground scraping their sides and legs, celestia weakly stood up and walked towards the door but was losing balance and tripped. When she did she hit a book shelf which caused it to open to a secret passage way.

Celestia tilted her head
"I wonder what's down here"
Celestia walked in a noticed a flight of stairs that lead down to a room
"This is new"
Celestia walked down the stairs until she reached the room, she opened it and saw a book sitting on a stand. She got closer to the book and noticed the tile
"The book of wars, I've never heard of such a book"
Celestia opened the book and began to read aloud
"Equestrian war, was a war created by disharmony and chaos. Most ponies turned against one another while others died trying to stop it, the only ponies capable of stopping such a war where six brilliant and magical mares."
Celestia stopped
"Six mares"
Celestia continued
"The six mares had strong and magical elements that could stop even the lord of chaos himself sadly the elements couldn't stop a war, so using their elements in another way they stopped the war and became the most powerful mares in all of ponyvile"
Celestia stopped
"Used their elements in another way?"
Celestia thought for a moment until it hit her
"I know what to do"
