What quiet is made of
Some materials take the room down a level. Obsidian comes out of a lava flow that cooled before crystals could form, so its surface is smooth and slightly waxy rather than sparkling. Matte silver returns no clear image of anything. Woven cord weighs almost nothing and takes on the temperature of whatever is near it. None of these announce themselves. That is the point of them.
Where it comes from
Obsidian is not rare, and it is not precious. It is what happens when molten rock reaches the surface and then loses heat quickly — at the edge of a flow, in a thin flow, or where lava meets water or ice. The same slow cooling underground produces ordinary crystalline rock. Only the fast cooling produces glass.
How it has been carried
Polished into mirrors in Mesoamerica, ground for use around the eye in Egypt, knapped into blades in North America. On the plateau it sits closer to the body than to the eye: against the skin, in a pocket, in a pouch. Not shown. Kept.
