All irregularities will be handled by the forces controlling each dimension. Transuranic heavy elements may not be used where there is life. Medium atomic weights are available: Gold, Lead, Copper, Jet, Diamond, Radium, Sapphire, Silver and Steel. Sapphire has been assigned.
Sapphire is -- everywhere.
Now she is here.
(Mostly. Not by mass -- most of her is there, and there, and there. But her attention is here.)
(Really, an immense equation in spacetime has been factored, and one of its many solutions is at this point, taking this form. But for human purposes: Sapphire is here.)
The irregularity, also, is here. To Sapphire's timesense, it radiates tangles, contradictions, age: something very ancient, something winding sinuous through Time... something, more than usually, alive.
To the human eyes Sapphire is borrowing: a shining snake, metallic, mirrored scales and mirror-face reflecting a hundred shattered worlds.
Sapphire is very good, but today she is alone. Today she approaches a shade too close, moves a shade too slowly.
Sapphire is good, but -- the snake is better.
Sending out ripples as it tears through Time to move, the creature rears back its head and strikes at Sapphire. This part of her -- small, humanlike, female -- passes through its maw.
Sapphire was here. Now she is not.
