Crimson Night

(A/N I don't have the patience to revise the last chapter so instead I decided on this little bit of sidestory. sorry for wall of speech heheh...hope this clears some things up)

“Nightmare Moon. Dim Sun. what do these two have in common?” Celestia asked. Twilight had asked her to explain Dim Sun and Lucifer, Celestia was starting with Dim.

“They both manifested as a sort of alternate version of you and Luna.” Twilight answered.

“Yes. It is Alicorn magic. When an Alicorn experiences extreme Loneliness and longing for a lover, one is created.” Celestia explained.

“But wait...then why was Nightmare Moon evil? And why were you forced to Banish Dim Sun?” Twilight asked.

“For Luna and Nightmare Moon I know not for certain...but from what she has told me and from my observations I theorize Nightmare Moon fell to corruption by manifesting with some of Luna's darker thoughts and emotions. When the ponies slept during her night Luna cared not. This created a rift between them and Nightmare Moon grew resentful of the one she was supposed to love. Luna told me she never loved her alternate self like she does you.” the Sun Goddess explained.

“Then what about you and Dim Sun?” Twilight asked.

“That was...difficult for me. Fearing she was going the same way as Nightmare Moon, she attempted to overthrow me...it failed...she came to her senses but the damage was done. I would explain further but...but it is for her to tell...not I. If it was completely up to me I would have not done anything and just turned to forgiveness...but my little ponies demanded punishment so I banished her to the Underworld...it was the first and only time I ever felt resentment towards my little ponies as a whole...but that is the past. Now is the present.” Celestia continued to explain.

“I understand that...now...I want to know about Lucifer and how somepony so powerful went down so easily...” Twilight said.

“Of course. Discord had a twin brother. But instead of enjoying chaos, Lucifer enjoyed death and destruction. Luna and I, with the help of Discord, sealed him away in the Underworld...Tartarus became what it is today in order to protect that.” Celestia said.

“Discord helped?” Twilight asked.

“Discord isn't evil. He's just dangerous. If he were to prove he can control himself he would earn his freedom...but the last outburst hurt that a little bit. The four of us were friends as Foals. Lucifer turned evil and Discord became detached from the ponies.” Celestia answered.

"So why was he so easy to beat?" Twilight asked.

"You had all of your friends, Luna and I there lending you all of our power. nothing could have defeated you." Celestia said with a grin. Twilight smiled back.

“There's only one more question I have for you...” Twilight said.

“And what is that?” Celestia asked.

“Um...is it possible for two Mares to have a Foal via magical means?” Twilight asked. Celestia smiled.

“Yes. It's very possible.” she replied.
