Origin Story
From: Oieffur Alchemy Hall · Silo, The Language-Reader
Re: The secret sealed inside the obsidian casket
"Every artifact waits for its person. Mr. Spade won't tell you this, because he believes the waiting is part of the answer." — Silo
Dear Traveler,
Mr. Spade never explains his work.
He returns from every journey with something tucked inside his coat — not gold, not trophies, but something harder to name. The smell of rust and scorched earth from a ruin. The particular silence at the bottom of a dry well, the kind that presses against your ears. The way candlelight bends around a blade at the exact moment it meets skin. He melts these things down. Pours them, together with platinum silicone and old formulae, into a shape. He lets the shape remember everything so that he doesn't have to.
Every artifact in Oieffur's hall is more than an object. It is a moment made solid. A feeling given form. When you hold one, you are holding something that actually happened.
The Sealed Casket is another matter entirely.
It belongs to no one yet. Mr. Spade sealed his creations inside, turned, and walked away without looking back. He believes the one that is meant for you does not need to be chosen — it already knows the way.
I have touched every artifact that has ever gone into this Casket. Read them with my fingertips — their weight, the mood living inside each ridge, the particular quality of presence that only becomes clear once everything else goes quiet.
But I have no way of telling you which one is already on its way.
I can only tell you this: it is not empty. The moment it reaches your hands, whatever story it carries — that story becomes yours.
— Silo, The Language-Reader of Oieffur
Size Guide
"Dimensions are facts. Sensation is interpretation. Alchemy permits neither to be absent." — Mr. Spade
"I learned to tell large from small not with my eyes, but with my skin. It is a more honest system of measurement." — Silo
Size S
Total length 18.5–24.0cm · Insertable 14.0–22.0cm · Max diameter 4.0–6.3cm
Make a circle with your thumb and index finger. That's roughly where S begins — between "just touching" and "comfortably held in one hand." For first-time travelers, this is Oieffur's designed entry point. You won't be overwhelmed. You won't feel empty.
Size M
Total length 23.5–31.0cm · Insertable 16.5–28.0cm · Max diameter 4.9–7.9cm
This is the size where you notice it has opinions. It no longer simply accommodates your body — it enters with its own shape and asks you to adjust. A gentle kind of insistence. For travelers with some experience who want fullness and texture to coexist.
Size L
Total length 27.0–37.0cm · Insertable 19.5–34.0cm · Max diameter 5.8–9.3cm
L has the widest variation of any tier. Dragon's Embrace and Nagaros sit at opposite ends of the same pool — the experience between them is not comparable. You're here to find where your limit is, then move it.
⚠️ Silo's note: L-tier artifacts vary significantly in depth. If depth-sensitive, leave a note at checkout — we'll try to accommodate.
Size XL
Total length 32.0–40.0cm · Insertable 24.0–37.0cm · Max diameter 7.1–11.0cm
Silo took three times as long as usual to speak after touching the XL pieces. When she finally did, she said: "I don't know how to describe it. I only know that once it has been inside you, you will remember it for a long time."
⚠️ Silo's note: XL-tier depth spans 13cm of variation. Recommended for travelers with prior XL experience.

Material
"Platinum-cure silicone. Not an adjective. The name of a material. The body verifies everything — it has never forgiven a lie." — Mr. Spade
"When I touched it, the first thing I felt was not its shape. It was warmth — slow, like something waking." — Silo
Platinum-grade silicone. Thermal response: warms to skin temperature within minutes of contact. No detectable scent. Rebounds immediately upon release, with no memory of deformation. Surface response remains identical throughout its lifespan.
Hypoallergenic. Phthalate-free. SGS certified for long-term skin contact.
(Silo's note: Care is simple — warm water and antibacterial soap, or a dedicated toy cleaner. Store in the included silicone pouch or a breathable bag. Water-based lubricant only. Silicone-based lubricants will gradually damage the surface, and Mr. Spade will be displeased.)
Closing
The Sealed Casket does not announce. Does not explain. Does not apologize.
The truth of desire lives inside uncertainty. Whatever can be anticipated has already lost its sharpest edge.
This Casket rests on an ancient premise: that the judgment of alchemy is closer to what you truly want than your own selection.
Choose your size. Seal the contract. Wait.
The alchemy has already begun.
(Silo's postscript: I know waiting is difficult. Every day at Oieffur I have been learning to bear the weight of sensations not yet arrived — but I can tell you, the moment it does, it is worth it.)
