She must have slept, Mercy told herself later; must have done so, because she dreamed. She was standing in the entrance hall of the Library, one hand resting on cool marble. The other hand held a small book; it seemed she had been reading. Those who had interrupted her were walking down the middle of the hall and Mercy’s heart leaped to see them: they had come back, at long, long last. Their year’s absence was ended and they had come home. Smiling, Mercy swept down into a bow.
The Skein acknowledged her with their customary remote smiles. There were two of them, one male, one female. They were twice Mercy’s human height and their long robes fell to the floor as smoothly as water, a pale, fluid grey. The male Skein’s skin was night-black, underlain with gold, and black hair reached his waist, tied with a gilded thong. The woman was white: snow haired, paper pale. Her eyes were jade; his were azure. They were talking and laughing in their own unknowable tongue, a language in which every word held weight, and their long hands glided in graceful, sweeping motions, adding emphasis to their words.
“You’ve come back,” Mercy breathed, and bowed lower. But when she straightened up again, the hall was empty. The Skein had gone and the marble paving was blowing with dust and cracked with age. It frightened her so much that she woke into the unfamiliar confines of the guest house, and she did not sleep again.
