**Canterlot Castle, after the mane 6 defeated Nightmare moon**
Celestia was helping Luna to her room, the experience leaving her rather weakened. "Thank you, truly. Istill can't believe you'd take me back after the things I did." Luna says with a sigh.
"Hey, no matter what happens, you'll always be my sister." Celestia assures her.
"Do you think they will ever forgive me?"
"Give them time. I'm sure they will." she says, helping her onto her bed. "Right now, you should be more concerned with regaining your strength. I can take care of things until you're atyour best."
"Thank you. But, where is harmony? I have to see her."
"I don't know how to tell you this, but nopony has seen her in a thousand years."
"WHAT?! What happened?"
"Nopony knows... She disappeared after you uh, went mad."
"I have to find her!" Luna shouts, starting to get up.
"I know how you feel, but we can't do anything for now. We'll find her, you have my word."
"But I..."
"Would I lie to you?"
"You are right." she says, laying back down. "I just hope she is safe."
**Ponyville, several months later**
It was late one night, and a dark figure staggers through the streets groggily. It blindly wanders until it smacks into the door of Twilight's home. It soon passes out on her doorstep.
Spike wakes with a start. "W-what was that?" he asks nervously.
Twilight wakes, looking over at him. "What's wrong?"
"I thought I heard something downstairs."
"It's probably nothing. Try to get back to sleep."
"Don't you think you should look into it?"
Twilight rolls her eyes. "If it'll make you feel better, I can have a look." she says, heading downstairs. Spike is close behind. "Ok, just where did this supposed sound come from?"
"The front door I think."
She nods, opening the door. "See? there's nothing to..." she looks down, spotting the figure. "What the hay? Spike, help me get her inside." They carry her unconcious form inside, placing her down gently.
"You see? I told you I heard something!" Spike says, scowling a bit.
"Ok ok, you were right. I'm sorry." she says with a sigh. "Ok, lets get a good look." she says, turning on a nearby light. She gasps as she sees a young alicorn, specificly Harmony. "What in the wide world of Equestria? She looks to be an alicorn, but she doesn't look familiar."
Harmony starts coming around, looking around in a panic. "W-where am I?
"Whoa easy, you are safe here." Twilight assures her. "I'm Twilight Sparkle, what is your name?"
She starts calming down a little. "My name is...." She clutches her head in pain. "Who am I? Why can't I remember?"
"You can't remember anything?"
"Just one, an image of a white alicorn flying towards me. Followed by a bright light"
Twilight thinks for a moment. "A white alicorn? Only one comes to mind. Does the name Celestia sound familiar?"
Harmony gives it some thought, but then a panicked emotion hits her. "Tia, Lulu..."
"So you do know them?" she asks.
"I don't know. The name does seem familiar."
"I can take you to see them in the morning. Maybe they will know something. You are welcome to stay here tonight."
"Thank you, truly." Harmony says, getting comfortable.
"If you need anything, my room is right upstairs, ok?"
Harmony nods, trying to get some sleep.
Twilight and Spike head back upstairs. "I hope she'll be ok." Spike says.
"I'm sure the princesses will know something. Until then, she just needs rest." Twilight tells him.
As Harmony slept, a dark aura approaches her, entering her mind.
**Harmony's dream**
Harmony is surrounded by darkness. She looks around, confused. "Where am I?" She hears somenone chuckling darkly. "Who is there?"
"A friend, perhaps. You wish to remember your past? I can help, for a price.."
"I-I don't know, something seems off."
"Turning down my gracious offer? Well, color me insulted." the voice says in a huff.
"Well wait, what exactly do you want in return?"
"Let me into your mind. We can share your body, and in return, I'll help you remember what you forgot."
I don't know... Can I trust you?." she asks, still unsure.
"If you doubt me, I could always find someone else."
"Could I at least give it some thought?"
The voice sighes. "I suppose, but keep in mind I won't wait forever."
