The Solution

Solar was flying at top of his ability. He needed to get to the DJ to get the preparation done. Skyra was on his tail, following him on the route to Vinyl.
"Are you sure we can get her so far to go all out with her music?" Skyra asked a little concerned. But Solar smiled.
"She's a DJ with awesome music made for being played out loud. It would be a normal routine for her." Solar said with a grin. Skyra however looked up. The sun was setting, she remembered that the wedding was in the afternoon. They weren't late so…

"Solar, the wedding is tomorrow, we have still enough time to get everything back to normal without affecting other ponies. "Skyra realized and told Solar. Who looked back with a raised eyebrow.
"You sure about that?" He looked up.
"Now that you say that… You're right, it's getting night." Solar added. He quickly turned around when he noticed something pass them on a higher speed and hover right in front of them. Solar stopped and landed he didn't expect anyone so stayed cautious.

"Hey guys." A happy Blade said. He just knocked on the door of Vinyl.
"I was just about to ask if Vinyl saw you guys, you were gone for some time but, since the Doctor was also gone, I thought that you would just be sometime else." Blade said with a little more seriousness in his tone. At the same time, Vinyl opened her door and looked to the situation.
"Solar, Blade my main Stallions, What can I do for you?" She said happily, almost pulling them inside.
"Want to test out the add on Blade?" She asked with an evil grin but was interrupted by Solar's hoof.

"Vinyl, we need you to play very loud tonight. And it needs to be tonight. Loud enough to produce specific amount of sound waves on a certain frequency so some threat that can only be extinguished with music because they can't be touched." Solar finally stopped talking and breathed heavily.

"Solar…what have you" Blade started but got interrupted
"Done, that will cost ya extra, but I'll do it." Vinyl said and smiled. She then went inside to get her stuff, then looked to Blade.
"Blade, you mind looking at the add-on later?" She asked a little guilty, but Blade hold up his hoof.
"I was going to tell you that I wished to have another appointment. AJ said she wanted to have dinner tonight. And I forgot to tell her that I had an appointment with you so…yeah." Blade scratched his head.
"Okay so it is a deal. Later Blade, please lock up for me." Vinyl grabbed some stuff and went outside with Skyra and Solar, leaving Blade behind.
"Have fun guys, we need it these days." He said after them and they disappeared in the darkness of the night.

In the meantime the Doctor and Derpy arrived at the studio of the other musician of Ponyville. Miss Octavia. They walked in normally to make sure they get in without being thrown out with the label of crazy fan given to them by the security. Within a few minutes they arrived where Octavia resided. She just walked out of the room when she saw the two other ponies.
"Mister Doctor, Miss Hooves, how can I be of service to you? The performance isn't until tomorrow I recall?" She asked them in her usual charming, but monotone voice.
"Miss Octavia, I don't wish to make you feel uncomfortable but we need you to come with us right now, it's a matter of urgency." the Doctor started and Octavia started to look confused.
"Octavia, there are these aliens that are bluish and they want to kill everypony around here because they see us as food and…" Derpy stopped when the Doctor put his hoof in front of her mouth and took over.
"What my assistant tries to say is that we need your musical prowess to defeat a threat to Ponyville and maybe even the whole of Equestria. Would you like to give us your assistance?" The Doctor looked determined to Octavia who nodded, she grabbed her Cello and made a, take the lead, gesture towards the Doctor. Together they left the studio and made way to the appointed meeting place.

Vinyl saw the others first and began to wave to her musical friend.
"Hey Tavi! You the other musician they talked about?" She asked and made a hug gesture to Octavia, who ignored it and just nodded to her friend.
"Aww, you're no fun Octavia, unlike Solar and especially Skyra, when I hugged him, she totally…"
" Vinyl!" Skyra yelled angrily and she had a look that could truly kill another pony. Vinyl Scratch hid behind Octavia and laughed while Solar began to blush. The Doctor broke the chaos with the usual bigger Chaos. He just tried to help set up the devices Vinyl brought with her and accidently dropped one of the devices. All the other ponies turned and looked at him.

"Not my fault, it was already rigged to fall when I stood here." He said with a innocent smile and Derpy looked stern at him for that lie.
"Hold on Doc, let me take care of my stuff, where does the sound need to go?" She asked while levitating the devices with her magic.
"Towards Ponyville, Town Square. The source is there, if we're done and there is no trace left of the portal then we can rest easily until tomorrow." The Doctor explained and they nodded. Vinyl was done with setting up her table with all kinds of buttons and Octavia set up her Cello and assumed position. Vinyl also set a special microphone near Octavia's Cello so her sound would be better audible. The Doctor grabbed a pair of weird looking binoculars and put it on his head. When he turned around the other ponies began to laugh.

"What? This is a very sensitive detector, with this I can see if the sound levels are good and if I need to adjust the settings." the Doctor explained, still wearing the silly binoculars. He looked towards Ponyville and saw some strange dots moving on the detector and one big spot in the Town Square.
"Okay, it's working. Now all we need to do is carefully seeking out the right sound level and then…"
"…WE DROP THE BASS!" Vinyl yelled and she powered up her music. It began playing through the speakers and the doctor saw the spots reacting to it and they began to close in.
"Too soon Vinyl, too soon!" He said and began adjusting the speakers to the noise that could destroy the beings. Octavia noticed that the damage had been done and started assisting her friend in making music to save Ponyville.

Ponies throughout Ponyville looked up the hill to look what was all the noise about. They were happy that there was music in the evening, who doesn't like some music? But they saw something else. Figures began half appearing. Bluish figures without faces closing in on the source. Some of them began to materialise some stayed out of phase with this world but all did the same thing. All the Devidians started to rush the hill, they knew they were in danger, their feeding grounds are taken away from them. The Doctor could hear their screams.

"Don't resist…Feed, we need to feed!...DIE!" The screams yelled. Every time the same sentence. The Doctor didn't pay any attention to it though, but it scared the others.
"Doctor! Doctor! Do something Doctor!" the companions began to yell but the Doctor threw his sonic into the air and caught it.
"Done, hit it girls!" He said with a smirk and Vinyl and Octavia began to play louder, closer to the mics. The Doctor looked through his binoculars, solar and Skyra stood next to him looking to the hill where the Devidians were suffering.
"It…seems kinda cruel. We're killing them." Solar said. He looked at the Doctor. Even though he had his binoculars on, he could still see the Doctor was looking with cold eyes. The eyes that said: To survive, these things had to be done.

One by one the Devidians fell. First the one that were into phase with this world and slowly also the ones that were out of phase. After a half hour the final dot disappeared, all Devidians have been dealt with.
"Thank you, miss Vinyl, miss Octavia. That would be all I dare to ask of you for tonight. But at the wedding you could still expact some." He said with his usual goofy smile. The DJ and Cellist laughed and packed their stuff. It was late thanks to all the preperations and setting up. They shared some goodbyes and hugs before going back to their homes. Leaving the Doctor, Derpy, Skyra and Solar behind.

"Well Doctor, where off to now? To the wedding I presume." Solar said, but he was tired. The doctor noticed it.
"I will bring you two home. And then I will see you at the wedding." The Doctor smiled as they all got into the TARDIS.
At the same time the TARDIS disappeared on the hill and appeared in front of Skyra's house.
"You kids have fun now and untill tomorrow!" The Doctor let them out and laughed. Derpy gave them both a hug and got back inside. The TARDIS made some noise and disappeared, leaving Skyra and Solar alone.
"So…You want to sleep here tonight?" Skyra asked carefully. She was hoped he didn't take it the wrong way, but Solar was just tired.
"I can sleep everywhere now. So if you don't mind, I'll accept you on that offer." Solar smiled and Skyra opened her door. they both went inside to sleep. Waiting on the final event. The wedding of Twilight and Blaze.
