The trick to reaching the woman was simply to get lost, or want to find her. 

As you walk along, a large tear would open in front of you. Of course, this anomaly would be indistinguishable from the rest of the landscape, only noticeable if you could sense energies, as they would be moving erratically amount, massive amounts appearing and vanishing. The only tell tale sign to any other beings is the fact that a tiny sensation would run through you, like a shiver, or a spark through your entire body. The sensation wasn't unpleasant, more just odd.

As you kept walking, if you were highly perceptive, you would realize that the landscape around you was fading slightly, like an old photograph. Vanishing around you, you would be left in a large, empty space.

Like a vacuum, it was blank, even footsteps making not a sound. 

After a short time, you would slowly become aware of a woman watching you. Black hair and white eyes, she wasn't blind; despite her looks, but simply had an absence of colour. She wore dark clothing, a tailored suit, with a waistcoat and black slim trousers, and a crisp white shirt underneath. She wore a small tophat, and it was decorated with raven's feathers.

She said nothing, simply looking at you.
