As Natalya stood there, at the edge of the yellow, staring, an outline of a door drew itself in the side of the box. This was startling enough, but she hardly had time to react to it before the door swung open and a rollaby fell out of it, as a consequence of the door being two feet above the ground.
The rollaby scrambled to his feet and stared around himself wildly. "Wh...what? How did—there's no door here! There's no, no space to occupy!" He looked up at the white wall behind him. "I guess that explains that, but
that just raises more questions! What is going
on?"
It was also notable to Natalya that the rollaby bore faint traces of color—not as vibrant as she imagined he ought to be, or as the patch of yellow on which he stood, but more than anything else around him. She didn't know what to think about this. "How did you get here?" she said.
