An Unnamed 39-Clues Crossover 1-Shot
Twilight Sparkle called her friends immediately after discovering what seemed to be a private document. As soon as the others arrive, Applejack immediately noticed the private document and recognized it. Sort of.
"This is a family history of... who?" Applejack asked.
Twilight looked at them. "That's the thing; it seems like all of the famous ponies in Equestria since the time before Starswirl were just related to one another. It's not like—"
"We're all related to him?" Fluttershy continued.
"Yes, but, how did you know that?" Twilight looked at Fluttershy who placed a photo of her family beside an M crest on the table. "Madrigal!? You!?"
Fluttershy was slightly startled. "Well, it was in the family to be egocentric and shy..."
Applejack went towards the door. "Let me get mah picture. Maybe it can tell me what Ah am." She left the room leaving the five ponies to think.
"Well..." Twilight gulped. "If I only knew Princess Celestia was also a Lucian..."
"What's more scary, the fact that history's most famous are related or something deeper than that?" Rainbow Dash questioned. "Come on, who cares if we're related?"
"Well, if it meant endangering ourselves because of our connection to the Elements of Harmony," Twilight began, "then it must be the reason why Ponyville is the center of almost many monster attack. Maybe Ponyville is a stronghold for one of these 'branches' that I still can't understand!"
The discussion was momentarily paused by Applejack carrying her photo album and placing it down and started to search for something. The others looked until they spotted a blue crest with a bear on a family photo.
"Tomas?!" Fluttershy recognized. "They're usually athletics, how come you're one?"
Applejack looked at Fluttershy. "Ah dunno."
"Well, looks like the secret's out then!" Pinkie took a piece of letter from her mane (don't ask) and showed it towards the others. "I actually went towards Ponyville to track Mayor Mare after killing my uncle."
Twilight took the letter which contained a yellow crest and read it.
Agent Pinkie,
You must head towards Ponyville and find the Cakes. They're our local Ekat residents, and I think they have intel about Mayor Mare who, as you might already know, killed your uncle who was supposed to be the next Ekaterina leader. Remember, beware the Madrigal.

Neuron Probe
"Neuron Probe? My science teacher!?" Twilight looked around. "I'm going for a spiritual walk." She then rightly fainted.
The five looked at each other before they pulled out some sort of communicator and turned it on.
"You guys are absolutely kidding me, you know that?" complained the pony which they all were communicating with.
"Why?" They all replied back.
"Because for all ponies to compromise your cover," the voice replied, "you just had to throw it off to a Lucian."
"Twilight Sparkle's a Lucian?" Fluttershy asked.
"Yes," the voice replied, "and she's my daughter."
"So Mrs. Velvet," Rainbow Dash began, "your daughter is a Lucian while your head of Madrigal? How does that even work?"
"You'll have to find that out," the voice replied as it disappeared into static. They hid the communicators, all evidence, and Twilight's document until they noticed something on the document itself.
Document #192
To: Twilight Sparkle
From: Lucian Agent "Mayor Mare"
Title: Cahill
I'm an inactive Lucian, and I got a feeling all of your friends are Cahills. I just knew it. In fact, I've been spying on Pinkamena ever since she came, and she's obviously related to the Ekaterina branch due to her inventive and creative way. I know your mother is a Madrigal, and you and your father are Lucians. If you manage to obtain any information, quickly message back.
Also, your castle will be used as a Lucian Stronghold. The 39 clues might've united all of us, but there are still those who want to kill other branches.
PS: Trust no one.
"Ah, now Ah get it. She wants to solve this mess," Applejack realized, "but she can't."
Rarity looked at Pinkie Pie. "Although I'm wondering how I could fit in, darlings, everything happened too fast."
The four looked at Rarity. "How so?" they chorused.
Rarity smirked. "Maybe because you weren't looking closely?"
Oh no.
A few hours later, Twilight Sparkle woke up from her position only to find that the area was a mess. Having forgotten the discussion and everything related to it, she decided to clean the room unaware that her friend was wreaking havoc in Ponyville. She ignored it and instead headed towards her bedroom and went to read a book.
While reading, Twilight began to wonder if she was part of a branch in a large family where she was related to her friends who, in turn, were at their own branches. Twilight immediately shrugged the idea off as it meant she was related to King Sombra in a way. She did have some sort of behavioral instincts which were similar.
As Twilight went off to bed, she could only hope that her friends wouldn't fight just because they were, if they were, related. That could ruin the principles of friendship, rendering the time they spent together useless.
She was about to sleep until a wounded unicorn teleported in her room, and much to her surprise, it was Starlight Glimmer.
"What are you doing here!?" asked Twilight. "What... happened to you?"
"Madrigals happened," Starlight replied, "they ruined EVERYTHING!"
Wait, what?
