Ah. I know what you're thinking. No, not everyone who tries to poke around disappears - most of them are sent away with bribes, threats, information false or true, or disappointment. I can't begin to tell you how many good-for-nothings come, expecting us to lavish them with attention and praise and youth. Feh!
I will say... the rumors are true. We, the Church of the Ebon Vault, commune with an ancient creature. We are his apostles, protected and guided by his power. Deep within the vault, he still lives. The first members of the church entombed him alive so that he could protect us for all time. Mahgdi Zaguri has, since then, assisted us with the preparation and encasement of both the Oversoul in the Vault as well as - well, let me describe him to you first.
He was wrapped still alive, eyes spiraling with mystical hypnosis. Tight bandages, infused with latex - then a thick layer of arcane rubber, and then many more. Engraved with magical runes and finally sealed up in his sarcophagus, our god still lives. His black lips and blonde hair look as pure as the day he came to us. He enjoys long periods of quiet and empty relaxation; thoughtless and mindless. No doubt his godhood needs this time to relax. However, when we beseech him, he awakes. His body wracks with pleasure, enjoying release after release after release and sharing his blessing with us. It's a sight to see.
In fact, you can see him right now! Well, you can't. Full members of the Church are granted access to a magical mirror, allowing us to see his face as though unbound... and even interact with him. But, don't, you shouldn't. More on that later.
As you know, our greatest power lies in the Ink that we produce. Magical potions that extend life and restore youth are something of a rarity, obviously, and are jealously guarded. You no doubt know that all such bargains come with side effects. Suffice it to say, our older members are somewhat... shinier than our younger ones?
Those older, more vaunted members of our Church eventually join him, sealed away in transcendent pleasure. They are mummified, layered, and masked. The Catacombs are filled with masked and hooded members, trapped and encased in the wall with only their golden masks visible. Remove them if you wish, but you'll only find the peaceful face of someone enjoying eternal arousal in communion with our Oversoul. These elder members channel their own sensations to the Vault, bringing him over the edge to new and unfathomable heights of orgiastic bliss and zen-like lust.
As you can see, there are many - like yourself - who wish to join our ranks.
At times, though, we need more members - more than we can induct properly. After all, consumption of our Ink and joining the Church of the Ebon Vault is a slow and cumbersome process, and sometimes we simply need fodder for his appetites. Sometimes acolytes are too deep to let go, but not of the caliber needed to actually join the sisterhood.
That brings us to this room.
As you can see, Elise - some secretary for some doctor - is about to be interred along with other "sacrifices." Folks of a sufficiently fetishistic mindset make for fine offerings to our dark deity.
Elise has been bathed, dressed, and treated like a princess at one of our spas. And, when it came time for her to settle the bill, we explained to her that she was to repay us with servitude in our catacombs. Tightly packed up in an enchanted latex suit, bound and sealed up in unbreakable orihalcum bonds, and locked away... it's quite a package, don't you think?
I know, I know, it's hard to resist. All that nice, shiny rubber, all her curves, that humiliating drainplug gag - it's quite a combo. She's already been stuffed full and fed the proper potions and reagents, so if you really wish to ungag her, we can. It can be fun to hear her moans and groans.
Hurry it up, though. She's to be interred as another emergency conduit for the Vault. Sometimes we simply can't contain lustful impulses, and additional choristers are needed. I theorize that he somehow draws our dreaming sacrifices into a magical dream of his own making. Sounds strange, I know, but unfortunately I can't very well ask our entombed little victims, can I? I'm sure they're having fun, whatever they're dreaming about.
Anyway, after others have had a bit of fun watching her, we throw that switch and get her good and packed. That gel slowly equalizes pressure all around her body, making certain that squirms are allowed but escape is impossible. The stronger she pushes or the more she bucks, the slower she moves. It's this sort of tech that lets us even grab our other newest acquisition, Sheila over there. (You really missed out, she's quite the squirmy package!)
Now that I've explained the tour to you all, I'm certain you're ready to begin the process of joining the Church of the Ebon Vault. There's more to learn, of course, but not all of you are going to be able to join us as full Sisters.
You - yes, you - over here. You've been selected...
