And what is time? A year is one complete passage of a planet about its sun. Any subdivisions of that year may be determined in accordance with other motions of the planet ... or the motions of its inhabitants.

For Jack, the four annual fluctuations of the Twilight represented seasons. Within these time units, dates were always to be determined more specifically by means of the stars-which were always visible-and the application of magical principles to determine the moods of their governing spirits. He knew that the daysiders possessed mechanical and electrical devices for keeping track of time because he had stolen several of these. But since they had failed to function darkside, they had been of no use to him except as trinkets to pass on to tavern girls as amulets of great contraceptive power.

Stripped and stinking. Jack stood upon the shore of that dark and silent place. After catching his breath and recovering his strength, he began his eastward trek.

The land slanted slightly upward, and there were puddles and pools of filth all about him as he made his way. Rivers of it ran to the lake, since all filth eventually comes to Glyve. Fountains occasionally erupted, jetting high and spattering him as he passed. There were cracks and crevasses from which the odor of sulfur dioxide constantly arose. Hurrying, he held his nose and prayed to his tutelary deities. He doubted that his petition would be heard, however, since he did not feel that the gods would devote much attention to anything emitted from this particular portion of the world.

Moving on, he rested little. The ground continued to slope upward, and after a time small crops of rock began to appear. Shivering, he picked his way among them. He had forgotten-purposely, of course-many of the worst features of this place. Small, sharp stones tore I into his soles, so he knew that he tracked bloody footprints as he went. Faintly, at his back, he could hear the sound of the many-footed things that emerged to lick at them. It was said to be bad luck to look back at this point.
