The doors swing open easily, with almost no sound. As they open, you can see into the room on the other side. It is a small chamber. The door you have just opened is in the middle of the long West side. The chamber is forty foot long, and about twenty foot wide. The South end of the room has a small dias, about six foot tall. Atop the dias is a polished silver mirror. It is a perfect mirror. The first any of you have ever seen. A small bronze socket is empty in the centre of the mirror. The mirror is a six foot diameter concave disk. The socket and focal point is about eight inches inset from the edges of the mirror. It is a gentle parabola. On the North side of the room, set flush into the wall, is a massive slab of dark and shadowy obsidian. It must weigh about eight tons. The obsidian plug is also circular. It has the same diameter as the mirror. The walls of the chamber are made of dull granite. There is no dust in the room. It looks fresh-built. Against the East wall, opposite the entrance, A stone shelf contains a few rolls of scrolls, wrapped in pigskin. From the entrance, you can see that there are about fourteen scrolls. Each scroll is sealed in its pigskin tube. They are arranged neatly on the plain shelf. A rosewood wedge on either side holds the scrolls on the shelf.
There are no visible inhabitants or perils in the room.

For Gnaeus Cornelius Papyrus:

Stratos Kopteros |

Stratos gingerly reaches out, and touches a scroll with his fingertip. Nothing happens. He breathes out, and opens the scroll.
"It is in Coptic Greek! We can.... I can.... read them.
...also true that no physician, in so far as he is a physician, considers or enjoins what is for the physician's interest, but that all seek the good of their patients? For we have agreed that a physician strictly so called, is a ruler of bodies, and not a maker of money, have we not?...
It is Plato. This scroll is by Plato. I am sure of it! There are annotations, in another hand. Marginalia. Open the others, and let us check if they are also Platonia."
Stratos smiles, and hands the scroll to Paper. He takes another scroll from the rack, opens the leather bag, and nods.
"This is also Plato. This must be a complete set of his works. The hand is the same. It starts in the middle."

Paper recalls the famous light weapon Archimedes was said to have made.
"My friends! this room is a parabolic array meant to concentrate light into a focused beam. Archimedes used one similar to this to ignite ships in a naval battle off Syracuse. Perhaps a beam of light opens a hidden passage?"

Levi Bram. |

"Levi obligingly mutters some Hebrew numbers, holds his fingers in a few symbolic poses, and conjures a light. He holds it at the centre of the parabola. The light reflects, but it scatters. The obsidian plug mottles and warps. Distorted views of a room beyond twist in the stone."
"This is not the correct light."

Rufinus Galsius. |

"The socket looks the right size for one of the torches in the passage outside."
Rufinus places one of the everburning torches in the socket. The fit is far from exact. Again, the flickering light reveals a way through the plug, but the light source is not properly used.
"What else gave out light in this tomb?"

Isat Vastra |

"The blue glow from the eyes of the dead, and I doubt that's a practical option. Or my symbol blasted light, but it won't do so unasked. We can try."
Isat takes out the strange symbol crafted by the underworld and holds it aloft.
Goddess guide us, what on earth am I doing, standing in the middle of a room holding your symbol?

In the room through the smoky and warping obsidian barrier, a circular light is visible. The distortions in the shifting black glass plug make it seem to flicker around. It is clearly the light you need, tantalisingly out of reach.
Perception checks please. One of you needs to get eighteen or higher.

Isat Vastra |

Gesturing to Paper to come closer, Isat examines the shadow cast on the obsidian plug.
"What did Plato say about shadows on a cave wall Paper? Can we manipulate this shadow to move the light in the next room do you think ... something like that ..."
As he thinks aloud, Isat explains his theory of the solid shadow to the others. so everyone can look at the spoiler

Isat Vastra |

Undeniable, but who's to say that Isat hasn't been boring Hrothgar witless with such stuff? I don't think Isat considers his audience much and he's an Olympic level bletherer. I can see them back in Constantinople, when the only worry any of them had was who was buying the next round, swapping stories. Hroth sharing the secrets of gelding people, Modius showing off his forgery skills and Isat getting blasted and wittering on about whatever took his fancy.

Allegory of the cave
Wiki has this to say.
Plato believed that truth was gained from looking at universals in order to gain understanding of experience Humans had to travel from the visible realm of image-making and objects of sense, to the intelligible, or invisible, realm of reasoning and understanding. "The Allegory of the Cave" symbolizes this trek and how it would look to those still in a lower realm. Plato is saying that humans are all prisoners and that the tangible world is our cave. The things which we perceive as real are actually just shadows on a wall. Just as the escaped prisoner ascends into the light of the sun, we amass knowledge and ascend into the light of true reality: where ideas in our minds can help us understand the form of 'The Good'.

Now that Isat is concentrating on it, he feels a strange sense of resistance to his gesture. The shadow of his hand stretches out toward the light, and Isat feels a warmth on his hand. The light is about the size of a hen's egg. Isat is now holding the light, through the barrier, using the shadow. The barrier is still part opaque and part translucent. Oily darkness flows in the plug. As Isat pulls the light toward the barrier, he feels a slight sense of weight in his hand. The light floats through, clutched in his hand.
It is intensely, blindingly bright. Not as strong as sunlight, but very hard to look at. There is no substance to it. Isat's shadow suddenly flips around, as the light source has changed. The light makes all of you cast really strong, deep shadows.

As soon as the light enters the socket, the parabola catches the light, and focuses it into a beam of glorious light. Isat, Paper and Modius were in front of the light, in the beam. Their shadows are now completely on the far side of the barrier. Abruptly, they vanish, and re-appear on the far side of the obsidian plug. The plug is now visible as if it were slightly smoky glass. What dust there is in the room, refleclts the light like a ray of God. Outside the beam, light is not as bright.
Isat, Paper and Modius:
