Day And Night

The train roared at us. I closed my eyes before the impact.
Then... silence, broken by her voice
"It's gone."
Trembling, I opened my eyes. Only the grey mist swirled silently around us.
"You have witnessed it. Remember well. Now, I move on."
Take me, please -
"No. Day and night meet but never dwell together. It is time for you, too, to return to your people."
I can return?
She hugged me and then, like the remnants of a tremulous dream, there was a shadowed silhouette, perhaps that of an eagle, becoming one with the mist.
And she was gone.
