Helluva Loud Adventures.

(May 5, somewhere between Pentagram City and Imp City.)

The I.M.P Van arrives to the location and they all come out to see where they are, and it seems like a very large facility, or an old factory that was once used to make heavy duty weapons for war, and it has some disfigured images of Lucifer and his faction.

The ones who have come to see this place are Lincoln, Luna, Loona, Moxxie, Millie, Lucy. Blitzo and the one who led them to this place, Velvet.

"Woohoo! This is it!" said Velvet. "This is where my special friends are, the friends that Val and Vox don't even know, so let's get going!"

They all follow the skipping Overlord, and are confused. "So, you guys know anything about Velvet and her so-called friends/associates? Because both names sound the same" said Luna.

"I'm not sure, heck I don't even know who the fuck are Tannins and Athena, and I got this odd feeling that they might not be good company, or am I doubting that vibe,"

"We can only know once we go inside and see what the fuck this is all about" said Blitzo.

They continue to follow the Overlord, and she knocks on the door of the double-doors of the old building. The doors then open and Velvet ducks and so do the others and molten lava is shot out and lands someplace else.

"Whoa! Looks like someone doesn't like us" said Lucy. "Or was that some kind of trap that you didn't mention to us?" They all look sternly towards Velvet.

The Overlord then recalls. "Right, they have that stuff in case someone who doesn't know them tries to steal what they got, not come on." They follow Velvet and yet didn't like where this was going.

They walk into the place and are shocked by what they see, it's a large laboratory with tons of stuff the normal mad scientist or serious professor would use, and seems like something Lisa Loud would wanna be part of, and glad she ain't here.

Another part of the room looks like a black smith and has tons of weapons that are setup and ready to be reforged into something else, and they see tons of other leftover metal, from the exterminators last year, a large stairway leads to the second level of the building and it seems restricted.

"Where the hell are we?" asked Millie. They are fascinated by everything, and then Lucy sees the many jarred demon heads and organs and a large tank of blood. They even spot a bomb that's being built and it's unfinished.

Then Velvet yells out. "Tannins! Athena! Velvet is back baby! Now where the fuck are you two hiding?!"

Then they see two figures appear. One not looking at them but studying something on her table and the other one is at the top of the catwalk and smiles towards Velvet. Who the fuck are they?

Tannins.
She is known as the White Death, and likes to experiment, and her sexuality is straight.
A 30 year old sinner. An introverted scientist who was sent to hell for experimentation on humans, but not for Incognito Labs. She now spends her time recording the names of specific sinners who died during the experimentations, usually higher ups or sinners with ties to higher ups.
Yet she still works in service to sell weapons to the highest bidder at the auction houses that Lucifer owns, she keeps record of all the weapons left behind by the exterminators.

Appearance: She has short blonde hair, which hands down from the sides and front, the back is tied up in a ponytail. Her skin is a pale white and her body is tall and extremely thin, with very narrow eyes and faint gray eye shadow.
She wears a large red glasses, hinting of her scientific position. She has a long neck which is covered by a black collar. She wears a white lab coat, and black gloves, as well as black boots. She has black horns that point up.

Personality: She's highly introverted and dislike all form of socialization, her only exception is through texting. She becomes highly uncomfortable and annoyed if put through eye to eye contact with another sinner. Besides her introversion, she enjoys experimenting with ne chemicals and other substances on more than unwilling lab rats. She rarely smiles, with usually only her sister in which she smiles around.

Athena.
Known as the Black Death, she likes to make weapons and eat other folks and her sexuality is Pansexual.
In her 30's and a Weapons Master, she was sent to hell for killing and eating other humans, in the process she used spears and other bladed tools to help with the body and hoarded any leftover bones. So, she's a cannibal.
Now alongside her twin sister, she helps clean-up the remains after the exterminators finish their job, she seems to like collecting weapons and checking if anyone is still alive, and if they are alive still then she'll kill them again,

Appearance: She's tall, and has a thin body, with grey-purple skin. Her hair is purple and bushy, as it hands far down behind her. Her eyes are bigger and more rounded than her twin sister, with freckles under them.
She wears a black sleeveless shirt with long gloves and stockings, having more flashy clothing choice, she also has horns which point up just like her twin sisters horns.

Personality: She's highly extroverted and loves to party and socialize. She will often go on for quite a while about her experience as a cannibal, making weapons and about girls and boy, etc. While she is a party girl, she avoids alcohol as she can barely handle a single drink.
She is like her sister and helps with the auction selling weapons, but she also helps run the black market and sell weapons there, she helps her sister fund the expereim4nts she does and she loves her sister and makes sure no harm befalls to her.

Athena comes down from the top of the catwalk and she lands in front of Velvet. "So, how's the old Battle Axe handling? Need some repairs?"

"Take a look." Velvet hands Athena the axe and the sinner takes a look to the weapon.

Athena checks the weight of the weapon and she looks to the sharp edges and sees something. "Alright, I think I can deal with this, all she needs is a fresh forge and then she'll be as sharp as she always was, and a good thing you brought her here too."

Athena then opens the blacksmith's vault and tons of molten angelic metal is seen. "I was about to open her up and make something, but now I can be able to forge something else by modifying your axe."

"Awesome, also I have some friends with me!" said Velvet.

Tannins sighs. "Velvet, you do realize that you bringing friends along is a violation of our affairs with you in creating and reforging what you require and the many times I need to…" Tannins turns around and sees who they are. "Well, this seems interesting and an acception."

Athena sees them as well and smiles. "Oh, friends! Well, hello and welcome to Tannins and Athena's legal and illegal weapons and experimentation, tell anyone and we will fucking kill you."

They all seem confused by these two sinners. Then Tannins goes towards Lincoln and Luna. "Hmm, the so-called adopted Half-Blooded children of the hellhound from the company known as, I.M.P, very interesting indeed. Now, I would require a sample from the both of you for further studying."

Luna then intervenes. "And if we say no?"

Tannins adjusts her glasses and looks to her sternly. "I wasn't asking, girl."

Loona then gets involved. "You're not doing shit to my kids, you cunt!"

Velvet then places a hand on Tannins. "Tannins, let's not do anything shitty. Leave them be and let them be here for what they need."

Tannins looks to the hand of Velvet. "Fine." She then removes the hand of the Overlord. "So, what is it you simpletons seek from us? Though, I could only assume that you are all here for weapons modifications."

They can feel this aura that feels like Lisa, but she seems far more devious and dangerous than Lisa could ever be. Blitzo then speaks. "Well, we could use some ammo and other stuff that we can…"

Athena then hands him a large box of ammo and other sharp weapons. "There you go and if anyone asks where you got 'em, do not tell anyone. We run the legal and illegal weapons sales in hell, and we don't like it when the folks we make contracts with double crosses us."

"She is not negative on that assumption" said Tannins. "We would rather have what we are establishing to remain in the dark from the ever so watchful eyes of Lucifer and any other Overlords, and which is why Velvet is the one we have trusted for some time."

Athena smirks. "Not even Valentino or Vox know about us." she then wraps her arms around her sister. "I would never let anyone come here and bring harm to my favorite sister."

Luna smiles to the emotions Athena is showing, reminds her of how much she would do whatever it takes to keep her brother safe.

Tannins smirks, then she goes back to her serious face. "Athena, my sister I am your only sister. We're twins." she then goes to the boy. "And what do you seek? Because ammo is not just the only thing you have in that human mind of yours."

Lincoln then shows them his claws. "These, I already added some modifications to make them far more impressive than they usually are, but I wonder if you ladies can do something else with them."

Tannins and Athena look to the gloves that are also retractable claws. "Oh wow. Now these are impressive and reminds me of that dream demon, Freddy Krueger. I think I can figure out what to do with this" said Athena.

Athena then puts on her gloves and the rest of her attire for a blacksmith. "But it's gonna cost ya and so will the ammo and weapons box too."

They knew this would happen. "Alright, how much are we talking about?" asked Loona.

"No, let me do this guys" said Velvet. "I wanna treat you guys to the weapons and other stuff they can do, so I am paying for this shit."

"Neither." They all look towards Tannins, and her twin sister smirks. Tannins then goes towards the group and hands them a list. "Within this list are names of those who have worked with Incognito Labs, how do I know is, none of your business."

"Now, I wish to experiment on them on what other intelligence they have contained, and that would mean that no matter where they are and what they are doing, they are to be brought to me so I may figure out how they work with their smaller to known wasted intelligence."

They see the list is long, and it's more than 56 staff members, and all scientists and some who are at the same ranks as the woman they took down, Dr. Caroline Linnaeus. They all look towards Lincoln, even Luna and Lucy wants to know what he thinks.

The boy then looks towards Tannins. "I myself, along with the others have made shadier deals with beings above your caste, but we'll do it. But, we can't guarantee on when we bring them to you, and we'll be sure they're going to be alive."

Tannins is unamused, and she's always like this. "I have less than high hopes that you shall bring forth what I seek, and ask no questions on why I need them. We will have your claws given to you on the following day."

"And you are so gonna love what I'm gonna do with them!" Athena then begins to start her work. "Also, we should hang out and party some time. I wanna know how it's been up there on earth too, been a whole since i…. Tasted someone."

The wicked grin she has was enough to make them decide to leave. "Well, we're gonna go now" said Moxxie. They all take their leave, and Loona grabs Velvet.

"Bye girls, I'll be back soon to get my axe!" They close the doors behind them, leaving Athena and Tannins to watch out the window as they leave.

"So, did they notice?" asked Athena.

"I do believe they didn't even notice the woman we have under our vanguard and considerate of my work." Tannins goes towards her experimenting table, and she walks by the chalk board which reveals the names of the people who have been sent to hell by I.M.P. One of them is Trump, and is now classified: Dead and Sinner formed. Even that Sinner form is now dubbed: Dead.

A jar with the head of Trump sinner is there, and on the table is the mutilated sinner remains of someone who was once named Jak, and in a cage and crying her eyes out, is a naked and chained Dr. Caroline Linnaeus, and her head looks stitched as if her brain was being poked earlier.

Tannins then looks to her next work. "Alright, time to see how this sinner can do with his kidney removed, then I can see how far his erection is when consumed by that woman." She then begins her experiment.

Tannins then pulls out a large buzz saw attached to a crane. "Now, to analyze the examples of this murders' brain, perhaps merging his mind with another would simplify the meanings of a combined evil thought, and help me see more on the dimwitted mind of killers and I do not count you dear sister."

Athena chuckles as she lets the molten metal pout onto the axe of Velvet. "No problem there sis!"

Tannins then goes to the cage and the woman inside cries and begs for her not to. "Oh hush up. This will be like last time, I poke into your head and the rest of you will pleasure the still conscious erections of my experiments, and if you die, then I care little. There will always be more."

Athena smirks. "Then I get to have what's left of them! I smell fresh meat." She goes to work and begins to open up the gloved claws, and then figure out what to do to make the boys claws more, dangerous.

To be continued folks!

A/N: They have met the friends of Velvet, which they never thought she had friends, and now it seems like they're going to be visiting them more often for some new weapons or modifications to anything they need on their next killing gigs. Leave a review and tell me what you all think.
