''I still don't believe them'' Rainbow Dash said as she closed the door behind her and started walking down the hall.
''There is no way I would do something like that!''
''I don't know Dash you might have just been sleepwalking'' Twilight said as she gave Dash a reassuring smile.
''Really now? Since when did you see me sleepwalking!'' Dash said as she looked at Twilight.
''Dash it can happen to anypony. No matter if they did it before or not'' Twilight replied as they walked out of the front door.
They walked a bit in silence after a while Twilight noticed one of Rainbow Dash's ears started to twitch more and more. When she wanted to ask her about it she suddenly started growling and shot straight into the woods and then suddenly Twilight heard a scream.

Twilight ran into the forest as she saw Rainbow Dash standing over somepony she had never seen before.
''Why were you following us?! Rainbow Dash screamed at the mare below her curled up in fear.
''Please don't hurt me!'' The mare with a gray/blue skin and light purple hair and eyes screamed out.

''Rainbow Dash?'' Twilight asked confused as she watched Dash standing over the unknown mare.
''She was following us!''
''And since when does being aggressive get you an answer?'' Twilight replied as she rolled er eyes.
Dash gave an annoyed sigh as she backed off.

The mare opened her eyes and stood up but then came face to face with a mad Twilight.
''Is this true?''

''Yes but I have a good reason!'' The mare said as she turned around to Rainbow Dash, ''I heard you got out of bed and started walking around without being aware correct?''

''Yes but-'' Dash replied surprised but quickly got cut off by the mare.
''There has been reports of this going on for years about this happening to ponies... It even happened to one of my friends.... If you don't snap them out of whatever they are in you will never see them again...''

Twilight let out a slight gasp but Rainbow spoke up ''And how do we know we can trust you? You were just following us!''

''I'm sorry I just needed to make sure you were alone'' The mare said in an embarrassed tone.
Rainbow Dash wanted to speak but quickly got stopped by getting a hoof shoved in her mouth from Twilight.

''Then why didn't the ponies that run this resort tell us about it?'' Twilight asked with a suspicious look.
''Because it's bad for business''

''Is is too much to ask for one simple vacation!'' Rainbow Dash said as she let herself drop to the ground.

''Please you have to help us! You're the only ponies that can....Anypony that went to search for what's causing all this haven't ever returned either'' The mare said desperate expression.

''We'll see what we can do'' Twilight replied with a reassuring smile.

''Thank you'' The mare said as she gave Twilight a hug.

''What is your name by the way?'' Twilight asked as she softly pushed the mare away.
''My name is Abi''

''I still don't trust her'' Rainbow Dash said as they walked the rest of the way back towards their vacation house.
''We should at least try Dash. What if she is right and ponies are disappearing because of it? If we do nothing this will just keep going!''

''Can't we go to Celestia and let her clean up the dirty work once?'' Dash replied as she got a pretty angry/disappointed expression from Twilight ''I guess that's a no''.

Rainbow Dash opened the door and waited for Twilight to go trough before following her inside.
''So what I'm just gonna be the bait?'' Rainbow Dash asked with a slightly annoyed look.
''Well you're the only one experiencing it'' Twilight replied as she grabbed a book from a shelf and headed outside again to lie down on a deck chair.

Rainbow Dash lied down in the chair beside Twilight's as they sunbathed until night time arrived with Dash sometimes deciding to go for a quick swim.

A couple of hours later

The pair decided to head inside to see if it were to happen to Dash again.

Twilight had made a simple plan to go after Dash and find the source of all this since it did not seem to affect her.
If they reached the source she would disable it and make sure Dash would not be harmed in the process.

However, things don't always go as planned.

Twilight was lying next to Dash as she watched her sleep calmly after a couple of minutes it would seem it started happening again Dash got out of bed and headed out of the door.

Twilight followed her every step as they walked almost the entire length of the island.
After a while, they reached a set of caves.

Twilight almost lost Dash as she started flying at high-speeds trough the caves.

After a while, they reached an opening.

Twilight saw what seemed like a huge crystal and she could hear whispers as she and Dash touched down on the cold stone ground. However, they didn't effect her.

Twilight walked up to Dash and touched her. As Rainbow Dash's head turned it was clear that she was still under the effect of this ''magic'' the crystal was generating.

''You have gone far enough!'' A dark deep voice said trough Dash.

''Who are you? Why are you doing this?!'' Twilight asked as anger crept up her face.

''That doesn't concern you'' The voice said as suddenly Dash turned around and kicked at Twilight but Twi quickly put up a magic barrier blocking the kick.

''Dash snap out of it!'' Twilight screamed.

''Aw poor little Twi is your marefriend hurting you?'' The voice said in Dash's voice with a grin.

Twilight gave a gasp as suddenly another kick came her way this time sending her back a couple of meters.

Rainbow Dash charged at her but Twilight quickly used her magic to throw her against a wall with a couple of tears rolling down her eyes.
Twilight charged her horn and send out a stream of magic towards the crystal when suddenly Rainbow Dash flew in front of it and the full beam hit her sending her towards a wall again.

Twilight let out a shocked gasp but quickly charged her horn again to destroy the crystal when she suddenly heard ''Twilight.... Please... ugh'' Dash said with slight tears rolling down her eyes.

Twilight quickly ran over to her and saw how bad the wounds were.
''Hold still'' Twilight said as she started a healing spell.

''Thanks for the help idiot'' The dark voice said when Twilight was almost done with the healing spell and then got a head butt by Dash sending her back a meter or 2.

''How did I fall for that?'' Twilight asked herself covered in bruises.
Twilight quickly charged up her horn again and pinned Dash to a wall soon after sending a beam towards the crystal cutting it in two.
As the crystal stopped giving off light Twilight ran towards Dash.

''Are you alright?'' Twilight asked still a couple of tears running down her face.
''I have been through worse'' Dash said with a reassuring smile as she tried standing up.

''Ow'' Dash said as she felt pain in her chest from the beam Twilight shot at her earlier.
Twilight gave Dash a hug but tried not to hurt her in the process.

''I'm glad you're back Dash'' Twilight said with slight tears.
''There is always time to cry later Twi go search for the other ponies I'll try and see if I can get moving in the meantime''
''I'm not going to leave you!'' Twilight replied.
''Don't worry I'll be fine!''

After searching deeper into the cave after a couple of minutes Twilight found almost an army of ponies that were just getting up again after being controlled by the strange magic after such a long time.

Author's Note

Soooooo this was supposed to be a long and in-depth chapter/series of events. But as I have said before I cannot seem to write those longer chapters anymore. Sorry again for it taking me this long to get another chapter done but I cannot find the inspiration to do these half of the time.

Hope you enjoyed this anyway.
I'll probably be ending this vacation story in the next chapter no idea yet what I'll do afterward.

I'm also thinking of maybe redoing some of my older chapters but we'll have to see whether I do that anytime soon.

Hope ya'll have a lovely day!

Brohoof!
