Answer:
Marking mortal privation when firmly in place. An enduring summation inscribed in my face.
I am the place where yesterday is always before today. What am I?
My first is second in line; I send shivers up your spine; not quite shining bright I glitter in the light.
I am quick when Iām thin. I am slow when Iām fat. Wind is my worst nightmare.
When I come in from sea to shore twenty paces you'll see No less no more.
It's what light turns into in the night
