"The band was wide, possibly of platinum. It bore a wheellike device of some reddish metal, with countless tiny spokes, many of them hair-fine. And each of these spokes extended a line of power leading off somewhere, quite possibly into Shadow, where some power cache of spell source lay. Perhaps Luke would rather have the ring than the sword. When I slipped it on, it seemed to extend roots to the very center of my body. I could feel my way back along them to the ring and then out along those connections. I was impressed by the variety of energies it reached and controlled - from simple chthonic forces to sophisticated constructs of High Magic, from elementals to things that seemed like lobotomized gods."
Roger Zelazny -- Knight of Shadows"The spikard made it easier than working out a transform spell. It was like a spell processor. I fed it the two end products, and it ran thousands of variations in a trice and handed me the finished products - a pair of spells it would have taken me a long while to work out along classical lines. I raised my hand as I hung them and accessed one of the many power sources the thing commanded off in Shadow. I fed juice into the constructs, watched the change commence, dropped my hand, and leaned forward."
