Gardner F. Fox, The Warlock of Sharrador
“ In answer to the high, keening notes, a tube in the great metal machine spanged shrilly. The tinkle of broken glass was loud in the sudden silence as Kael dropped his fingers from the quivering harp strings.Lunol, the peddler, cried out harshly, his face a wet mass of sweating fear. Flaith screamed high and shrill. Her bare arm lifted and pointed.The McCanahan whirled, and his harp fell from numb fingers.Bright and blazing, like the core of a giant sun, a whirling mass of fiery matter whirled and quivered, pulsing before the great machine. Its incandescence was blinding, brilliant. ”
