Wearing clothes with words on them cuts the number of random summons down enough they're not annoying. When one floats by anyway—yeah, she's bored.

Now she's somewhere else.

"Greetings, summon... wow. Okay. Loving the mechadendrites," says a tenctacle-less humanoid woman with tightly curly red hair, a baggy black t-shirt with the English letters PARAFFIN NEVER WORKS written across the front, dark red wings, and no soul.

It’s a good deal less monstrous than he expected, and it(she?) is speaking perfect low gothic instead of screaming horrible noises like the monsters in the footage. But he just summoned something with some kind of incredibly heretical witchcraft and so will take what he can get.

”Save me from the inquisition and you can have my soul! Anything! Just save me!” Alden yelps at her in a panic.

The inquisition is done knocking. Las fire is melting down the door and a power armoured boot is stepping into the room.

”Surrender now! How dare you block our access, heretic! If you resist arrest your death will not be quick!”

why do people keep offering her souls

she can't do anything with those and it's gone past embarrassing to irritating—on the other hand this place is weird and if his death is quick she has to go home.

"Sure," she says, and makes a that-a-kinda greyish-hard-nonmelty-thing shell around the melting door.

“By the Omnissiah*!” Alden squeaks out when the door is covered up sealed again. None of the monsters in the footage could do that.

(* the concepts in this word translate roughly as: God of technology/source of all motive force/god of mankind )

Alden wonders if swearing by the Omnissiah after just having done witchcraft is double extra heresy. Wait why is he worrying about if its okay to still swear by the Omnissiah when hes just committed witchcraft! He summoned something! And the inquisition will kill him for it! They were right there on the other side of that thing that appeared!

”Oh scrap, oh I’m so fucked. Why did I do this. I should have just killed myself like a normal person instead of summoning something! At least my soul would be safe then. Oh emperor, when the inquisition gets me they’ll torture me so long that my future great great grand nieces will still be able to hear me scream.” Alden is rambling and catastrophising, and the thing he summoned, while not looking like a horrible toothy monster, still is radiating a ‘wrong’ and ‘not human’ presence to it. Deep down he just knows its ‘other’, and now that thing has a claim on his soul!

Theres banging and the sound of las fire coming from the other side of the shell. Eventually the sound of plasma fire can be heard. The metal around the shell is getting rather red and glowy as the weapons fire dumps heat into the area surrounding the door.

Dude would rather be dead than have summoned her? Gross. She forms an immediate ambition to be way better for this guy than not having summoned her. Or possibly way worse, though it sounds like that's a gimme.

...better's going to take some more work. Is there another door? Should she make one? Two-hands-sized diorama of the immediate surroundings in coloured ice?

There is one door from this workshop to the hallway. The one she sealed.

The hallway has: a man in power armor and a coat and hat that a 21st century earthling would find very reminiscent of an SS uniform. Various other intimidating looking goons in non powered armor with laser guns. And a few…. Robot zombie looking things with robo tentacles like the summoner has. The robot zombies are the source of the plasma shots.

The rooms above and below and to each side look like more workshops like this one.

Alden is just hyperventilating and panicking. Part of him wishes he had upgraded his lungs so he could stop hyperventilating.

Akʰa has approximate knowledge of many Earth things but "nazi uniforms" did not make the voyage.

She melts her map in a puff of plasma then conjures specks of dust corresponding to the composition of - wow there are wires heading all through this place. How does summoner feel about electricity. Hmm.

Picks a largeish patch of floor. Appears circle of air thru the edges and the patch drops away, landing flat on the floor below.

"Hey dude! C'mon, let's move."

“By the Omnissiah!” How is it doing that! How powerful is this thing? Alden doesn’t know wether to be hopeful or worried.

The wall to the hallway is getting very red hot and melty looking. It wont be long before they get through. Alden jumps down the hole into the workshop below his.

”I need somewhere they wont find me. They’ll turn the this whole block upside down to find me, especially after what you just did. I didn’t know witchcraft could do that! But its very clearly witchcraft! They either think I’m a mutant or know I summoned something, the inquisitor is going to never stop hunting me down. Oh scrap oh scrap” He gets rambly and thinks aloud when he is stressed.

Akʰa floats down with warm air under her wings and replaces the floor ceiling seamlessly.

"You haven't met cool enough demons. Where's a not-this-block, what kind of way?"

“I only summoned you because I was about to die! You think I’ve done this before?” He lets out a slightly unhinged giggle. “I’m not even a cultist. I just copied what they did from footage I saw. The demons they summoned were much more toothy and stabby and eating peoples heads.“

If he was a mutant or heretic (and he IS, in fact, a heretic) … where would he hide…

”We need to go down, way down, all the way to the underhive. I Should be able to handle the lack of life support due to my augments, do you need to breathe?” The underhive is not very liveable but it’d be almost impossible to find him there.

Why was he talking to eldritch being he summoned with witchcraft as if this was just a normal thing to do!?! He wants to shut down and cry but if he does that HE WILL DIE.

Other thing that did not make the voyage from Earth to this here brain: working model of how weird it is to know nothing about demons a couple decades after Revelation.

"Man, eating people's heads is so boring. Terrible texture balance." Presumably they did... not eat their summoners/'s heads? Left those for last? Why would the summoner/s not dismiss... eh, whatever. "No need to breathe, I am not a thing that dies. You good to keep jumping?" Icy diorama of the straight below.

There are a few spots in the floor that have plasma conduits! Breaking those would be bad. So slight detours are needed rather than jumps straight down. And some rooms below are occupied.

Alden does not pick up on the sarcasm at all. Somehow hearing about it eating people makes him less scared. More within his expectations. So it was the kind of horrible murder monster he expected after all if it had opinions on head texture, it just looked more human than the others, and it could make (temporary?) holes in things. 

“We should take an elevator eventually. Before they get locked down. But another floor down at least probably wont have the halls guarded.”

Alden is correct to pick up no sarcasm! Hair and bone have awful mouthfeel, and unless former-ensoulment does wonders for the flavour brain is just dull... whoops, there goes her map. See she was so smart to check ahead!

Is there an unoccupied room straight a plasma-less floor-patch below? Or... any guards horizontal to this room?

In the corner of this room they safely can drop down into what looks like a janitors closet! In the 40th millenium they still use mops and buckets, a small room with mops and buckets is probably a janitors closet.

The hallway has one of those robot zombies, but who knows if that’s a guard robot zombie or not. The hallway in the floor below is empty.

Alrighty ho. She picks up the loose chunk of flooring and drops it through her next, cornery hole.

"Mind your landing, there's clutter."

Alden uses his thicker mechadendrite tentacles to lower himself down. Gosh this would have been a tricky jump with a baseline human body. How does anyone get by without mechadendrites.

”You are awful helpful for a man eating monster, I didn’t know my soul was so valuable.” He’s been panicking so long he’s getting a little numb to it. His brain has enough room to run his big dumb mouth now.

Kiddo, what you offered was anything... shouldn't bring that up until she's thought of something to ask for, it'll be awkward.

"It's the tentacles," she says drily. "They fascinate." Come to think of it, that's basically true!

She'll float down after, if there's space, or wait for him to exit the closet.

“You have not ever seen a member of the mechanicum before? Mechadendrites are pretty standard… they come standard on servitors too.”

Alden peeks out of the closer to see if anyone is in the hallway, makes sure the demon is following, and rushes down the hallway.

”do you have any way to hide the wings? It gives away you aren't human from a much greater distance.” This close the sense of otherness she gives off is rather strong and probably impossible to hide, if he wasn't so scared of death by inquisition then that feeling would bother him quite a bit. But if they covered the wings then people might not her at a distance.

Following! She flexes her wings out, then folds them back... somewhat. They're not obviously not-a-backpack from the front.

"It is correct for people to think I'm not human, because I'm not."

“Yes but if anyone else knows that they’ll shoot me! Even if you can’t die I can. Im really very vulnerable to being shot! If I didn’t mind being dead I’d just be dead instead of doing something as incredibly heretical as summoning a demon!” Now there’s any hope of survival, the idea of being shot is actually more scary. When there was almost no hope it was somehow easier to bear.

”If we can find something to cover those up we might make it to the elevator.” The main paths are usually at least a little busy, they won’t only see her from the front.

But is it really a big—she conjures a speck of water for each person in the relevant vicinity, just inside the top layer of her palm for better sensitivity.

ugh fine 'shoot the summoner' is reasonable response to unbound-demon she will try not to prompt any of those people to squint at her nonbindings. wings are useless extraneous baggage now, not Her.

"You'll also wanna stop—gah—babbling about it," she says, cutting the wings off with only a slight sprinkling of viscera, sealing both ends with skin, and...chucking them back in the cupboard, why not.

Should he be surprised the demon can casually cut off its wings like that? Maybe. It sorta makes sense that it could do that and be fine though.

Alden is no stranger to miscellaneous viscera.

”Okay at the end of this hall will be a more open throughway, don’t look anyone in the eye, stay close, let me do the talking. Maybe I can actually manage to get us into the underhive.”

Alden winces. “Then I guess I count that as being saved and you can yank my soul out and dance in my entrails or whatever it is you wanted with me.” Summoning a demon was such a bad idea, but it’s not like hes strong enough to deny the demon whatever it wants to do to him, and he did make a deal contingent on him being saved. Just because it ends in his probable death doesn’t mean he wont stick by the deal he made. At least its not whatever the inquisition would do to him.

He leads them to the end of the hallway and the main causeway is about as wide as a highway, just inside a building. There’s plenty of people walking down it, but theres enough space to avoid getting close to anyone coming in the other direction if you are careful with timing and pathing.

D'aww. Would she dance in this guy's entrails? (no. why. sticky and slippery. inferior dance experience.)

...he doesn't know she needs him alive, huh. Hmm. Well, between thinking about that and smiling ominously and observing the latest developments in Earth architecture she won't get too bored following him calmly.
