BISAA HQ Nº 1, Washington D.C.

You walk through the hallways of the freshly built building of the Bureau of Interdimensional Security Affairs Agency, or BISAA for short, you are Agent Jayson, you used to be from the CIA, but you were offered to join this new agency, and you accepted, the agency is just 1 year old, and already buzzing with activity, this is the Number One Head Quarters, the other one is in Equestria, Canterlot, the capital city of the magic land of ponies, it has been 2 years since Earth had got technology to make a portal towards another dimension, discovering this world full of small technicolor horses, at first, the ponies were scared shitless, but the leaders of the New Terran World Organization met with the pony leaders, and they both made an alliance, by then, 1 year later, they decided to make an agency to counteract to terrorism and contraband, mostly from this world, and so the BISAA was made, making 2 HQ's in each side of the portal.

Now, you are walking towards the meeting room, where you will be assigned your mission and fellow teammate.

As you round through the corner and open a door, your ears are inmediatly filled with noise, as humans and ponies alike walk to and fro the various rooms in the office, you haste towards the next door, and so on.

Finally you arrive to the final door as 2 guards flank it, one human and one pony solar guard, the both of them staring at you expectantly.

"Agent Jayson, I was summoned here." You say to the guards.

"Go right on through." The human answers as he opens the door for you, you thank them with a nod and walk through it, closing after you went into the room.

The first thing you see are 2 tall white and dark blue ponies with flowing mane and hair, the leaders of Equestria, Princess Celestia and Princess Luna, the next one is Secretary Phill of the BISAA and Superintendent Carlos of the North American region, all of them sat around a round table with documents.

"Princess Celestia, Princess Luna, Secretary Phill, Superintendent." You each give them a nod correspondengly.

"Hello, Agent Jayson, please sit down." The secretary gestures you to a chair infront of the table and you do as you're told.

"We assume you already know the reason you are here, Agent?" Princess Celestia asks you politely.

"I am here to be briefed about my teammate and deployed, that's all I've been told." You reply.

"Yes, well, about your teammate, here she is." The Superintendent says while dragging some documents folder closer to you, while gesturing you to open it.

You open it and look first at the photo of your teammate and name.

The photo is that of what looks like a combination of a bug and a pony, it's coat is black, it's mane is light blue, green slit eyes, horn filled with swiss chesee like holes, and fangs coming out of her mouth, by the looks of it is a female.
Her name is Chrysalis, class of pony is "changeling", gender is indeed female, her status is jailed/in rehabilitation.
You raise an eyebrow at the latter, Celestia notices and speaks:

"Reason is down more in the documents, you will have time to read it while we go to Equestria, but before, the reason for your mission." She says while nodding to the secretary.

"We've had recent reports of more contraband activity from Earth to Equestria, local authorities tried to catch them, but they seem to have little sucess, with only a trace of some boxes of cocaine and marijuana, whoever is contrabanding this, has access to a portal-opener, we don't know if they have more than one, but it is your mission to find out, we'll be telling you where to start, but the rest will be up to you." The secretary finishes and Celestia speaks again.

"Anyways, shall we be on our way to your new teammate?"

BISAA HQ Nº 2, Canterlot, Equestria

While you were on your way with the others to Equestria*, you've readed the full dossier on Chrysalis, apparently, she was a "Queen" of this "changelings" who invaded Canterlot but failed due to Princess Cadence and Prince Shining Armor's "power of love", yeah, this pony stuff can be really weird.
After some searching, they found Chrysalis scattered on the Equuis' "badlands", she was weak, Celestia was forgiving and put her in rehabilitation.
It costed her, but after all, she was cooperative, and was almost going to be reinserted back in pony society with a little help, but then recently the leaders of the BISAA decided she would work good as an Agent for the BISAA thanks to her metamorphosis capability.

You, the Princesses, the Secretary and the Superintendent arrive once again to a meeting room similar to the one back on Earth.
Inside just get outs a human with some papers, nodding to the group before he sets off, sitting behind the table is Chrysalis, she has been looking at papers infront of her before she directed her gaze quickly to the group of you, especifically Celestia, and smiles.

"Ah, Celestia," She then nods to Princess Luna "Luna," then directs her gaze to the remaining of you.

Celestia politely returns the smile "Hello, Chrysalis, I hope you are doing well," Chrysalis nods to her then looks back again at you as you all sit beside the table. "This here is Secretary Phill of the BISAA," She nods to the Secretary "He is Superintendent Carlos," looking to him "And finally, of whom I assume you have already been told, Agent Jayson, your partner for now." She says finally nodding towards you.

"I see, I have been told," Chrysalis says "Still quite strange, this BISAA, and the "humans"," Chrysalis seems to scrutinize you "Well, nice to meet you, Agent Jayson."

"Nice to meet you too, Chrysalis, and call me Jayson." You reply as you hold out your palm.

She looks at your holding hand confused, then raises her holled hoof slowly foward, you then grab it and give it a firm shake.

"Very well, Jayson," She says retracting her hoof and smiling.

"Alright, gentleman and mare, now that you have exchanged formalities, let's keep on," Secretary Phill says "Your first place to search will be in Ponyville, a small town at least 5 hours far from Canterlot, when you arrive, you'll have to go to Agent codenamed "Delta", but known as Derpy Hooves from the locals, she will be telling you more about the issue," He says and takes a deep breath, "That's all, good luck, your issued car is just outside the building, dismissed." He finishes, then motions both you and Chrysalis to go.

You and Chrysalis stand up, nod a final bye, then set off, Chrysalis wondering what is a car yet.

As Agent Jayson and now, "Agent" Chrysalis get out of the room, the occupants still there wait some minutes before Carlos speaks:

"Alright, bring in Agent Mack." He says firmly, they all nod, then Phill takes out yet another document folder with the red letters "TOP SECRET" on it.
