I closed my eyes and saw her:

A wedge of dark, wavy hair topped with gold and jewels.

She held a chalice made of thick, pale marble and filled with a dark liquid. She held it over a basin made of the same marble and filled with the same liquid.

And above her chalice hovered a golden orb which cast a halo over everything.

Who she was or what her potion, I have no idea.

I only know I saw her for a fleeting moment, and that it was important to remember.
