Destroying was a thousand times easier than building up. For Mard the neophyte to convert chaos to adamant—to say nothing of more complex things—would not have been possible. But melting adamant into chaos was a simple trick easily learned.

And so what transpired over the next few hours was that Mard and Querc, working together with her knowledge and his aura, and beginning with the sample that Fern and Lyne had fetched to them, melted away the adamant. Mab told them which parts of it to remove. It became chaos and dissipated like smoke, and what was left of the Cube seemed to dissolve like a chunk of ice left in the sun.

What began to emerge from it was a thing made out of iron. The first part to be exposed was a sort of handle, ornately carved with symbols that put Prim in mind of the decorations on the Temple complex of Elkirk. Below that for some distance was nothing but a shaft, thick as Burr’s thigh, oriented vertically within the Cube. Below a certain level this broadened and ramified into an extraordinarily complex tracery, the very look of which made them all glad that Burr’s sword had not come anywhere near it. Even the most talented sculptors of the faraway Teemings, working with their finest chisels, could not have freed this thing from the stone in which it had been embedded without damaging its finer convolutions, some of which were no bigger than hairs.

“It is plainly enough a key,” Edda said to Corvus, as the work proceeded. “Which means it must purport to be the key. You brought me here because only I can carry something that heavy. This all makes sense, to a point. But it is perfectly well-known to all learned persons that El destroyed the key to the Fastness. As Lyne was pointing out the other day, for El to have done otherwise would have been utmost folly. The merest glance at the complexity of that object makes it obvious that no copy or counterfeit is possible. So there is something to this whole matter that reaches beyond my understanding. I who was born in Camp to Eve, and saw Cairn kill Messenger of El, and drank the angel’s stuff into my form, and have dwelled in the Land ever since and been all over it, have no ken of what goes on here.”
