MLP AU Crossover Specials

In an unknown part of the multi-verse, a single male human finishes turning a giant vault door.

"Finally..." The human lets out before pushing the center part of the vault door. "With this, and the secret of saving worlds within, perhaps I can finally save everyone!" The human said. The fault door swung open suddenly before a mysterious power began sucking him inside. "What the...I don't think this was supposed to happen! No! No!" The human said before suddenly he lost his grip on the floor. "NOOOOOOOOOOOOOO!" He added before he found himself dragged by the mysterious force past the vault door. He was mysteriously turned into a horse-like creature before landing in some sort of castle.

The Vault of Secrets Part 1 - Side Dawn

Meanwhile, Lola and her new friends finally were able to recover from the massive quake.

"What the...what was that all about?" Luster Dawn asked.

"That...was the sign that someone used the Vault of Secrets incorrectly." Lola said. "My father told me all about that Vault and the secrets it holds. Many rumors about what the vault contains have spread across the multi-verse, but all of those rumors are all false. There is only one truth to the secrets the vault locks behind it's doors, with the only two people who know it's most valuable secret are me and my father." Lola said and got up from the bed.

"So, you have every plan to go and teach that no-good person a lesson then huh?" Cozy Glow asked.

"In a way, yes. Yes you could say that. And I think it's best if you come along. In order to know just how important it is that none of you ever use the vault outside of an emergency, then you must come with." Lola said.

"We weren't planning on letting you go alone anyways." Twilight said.

Lola lead the group through a massive forest area, far away from the likes of the Everfree Forest.

"It's this way..." Lola said before leading the group towards what looked to be a giant stone entrance. "Inside this structure is the Vault of Secrets itself. Now, follow my lead and do exactly as I do. In order to detour outsiders, the Vault is littered with traps galore, of us all, only I know how to disarm the traps inside by hand. Or hoof in your case." Lola said.

"Well I guess that would be better, but how are others supposed to disarm those traps?" Luster asked.

"Each trap has a riddle associated with it, and only someone with the right wisdom can solve each riddle to disarm the trap. But my father made me memorize each solution to the point where I can recall them by memory." Lola said.

"I see...so we really have no choice then to follow your lead." Twilight said as Lola lead them through the Vault.

Trap after trap was past and disarmed, until at long last, the group came up to a large Vault Door.

"Wait...what's this riddle about?" Twilight asked, pointing to the inscription next to the vault door. "To open this final door, think not what you have done, but rather what you have not done." She read.

"Great...so even the vault door itself has a riddle connected to it." Apple Buck said.

"I hate riddles!" Diamond Tiara said.

"The riddle is a trap." Lola said simply.

"SAY WHAT NOW?!" Everyone else exclaimed at her.

"Many take one look at that riddle and think what they have to do is turn the vault door a certain way to open it." Lola said.

"Well duh! That's what you do with vault doors right?" Scootaloo asked.

"Not this one." Lola said.

"...Come again?" Sweetie Belle asked.

"For this vault door, in order to open it...you simply do nothing." Lola said before using her magic to press the center of the vault door. Suddenly the vault doors opened up.

"I...don't get it..." Twilight said.

"Whoa...Twilight not getting a riddle? STOP THE PRESSES!" Rainbow Dash yelled out.

"It's like you read from the inscription: In order to open the vault door, think not of what you have done, but instead of what you have not done. And throughout this entire vault, what's the one thing we haven't done?" Lola asked.

"...Oh wait. I get it now." Twilight said.

"Err...mind filling the rest of us in?" Cozy Glow asked.

"It's so simple yet so complex at the same time: In order to open the vault door, we simply do nothing extra." Twilight said. "That's the trap isn't it? Someone sees a massive vault door, and their first rational thought is to turn it to open it. When the reality is, is that they don't need to do that." She explained.

"Right on the nose as they say where I'm from." Lola said and used her magic to get everyone down towards ground that was now on the otherside of the vault.

"Whoa..." Rainbow Dash said.

"This looks like ponyville, but it's not the same." Luster Dawn said.

"Indeed, that's the real secret of the vault: It's an interdemensional gateway to other versions of a singular universe." Lola said. "And it's very important that we change NOTHING here." Lola said.

"Why's that?" Cozy Glow asked. Suddenly she got a headache.

"Cozy Glow, you okay?" Luster Dawn asked her friend.

"I'm...I'm fine. But more importantly...I think somehow I know...I know why we can't change anything here. It's because of what's called a 'Universal Constant'; in order for the version of our Equestria to continue to exist, other versions of it must be kept intact as they are; even the slightest change we cause here can mess things up in our world." Cozy Glow said. "But...how do I know that? How COULD I know that?" She asked.

"I don't know...but that's a topic for another time." Twilight said.

"Well I honestly don't care. It's great we know now why we can't change anything here." Luster Dawn said.

"At least that much I can agree too, but that was a lot of egghead speech coming from Cozy Glow." Rainbow Dash said.

"I swear...I only just knew after I had that mysterious headache. I don't know how it made me know that, but it did!" Cozy Glow said.

"We can worry about Cozy Glow and her headache's later." Twilight said. "For now, we must figure out a course of action." She added.

"Don't worry, I got one." Lola said. "My father always told me that if I was to ever use the Vault of Secrets that the first thing I should do is find the source of the Universal Constant and form an olive branch with the version of them in the version of the universe I'm in." Lola said before turning to Twilight. "And in our case, the source of the universal constant here in the My Little Pony universe, is you, Princess Twilight Sparkle." Lola said.

"ME?!" Twilight exclaimed.
