And it was snowing.

Gingerly, she stepped into the closet. The instant her foot touched the floor, it seemed to expand to all sides. She stood at the center of a great wheel of doors, with all but two of them–to her office and to the winter world–shut. There were hooks beside each door, and hanging from them were costumes of a hundred different cultures. She thought she recognized togas, Victorian opera dress, kimonos... . But most of the clothing was unfamiliar.

Beside the door into winter, there was a long cape. Ellie wrapped it around herself, and discovered a knob on the inside. She twisted it to the right, and suddenly the coat was hot as hot. Quickly, she twisted the knob to the left, and it grew cold. She fiddled with the thing until the cape felt just right. Then she straightened her shoulders, took a deep breath, and stepped out into the forbidding city.

There was a slight electric sizzle, and she was standing in the street.

Ellie spun around to see what was behind her: a rectangle of some glassy black material. She rapped it with her knuckles. It was solid. But when she brought her key near its surface, it shimmered and opened into that strange space between worlds again.

So she had a way back home.

To either side of her rectangle were identical glassy rectangles faceted slightly away from it.

They were the exterior of an enormous kiosk, or perhaps a very low building, at the center of a large, featureless square. She walked all the way around it, rapping each rectangle with her key.

Only the one would open for her.

The first thing to do was to find out where–or, rather, when–she was. Ellie stepped in front of one of the hunched, slow-walking men. "Excuse me, sir, could you answer a few questions for me?"

The man raised a face that was utterly bleak and without hope. A ring of grey metal glinted from his neck. "Hawrzat dagtiknut?" he asked.
