Marlon’s hands flickered like firelight over the keyboard, changing some of the interface settings. Csongor was familiar with what he was doing, since he’d been forced to learn similar tricks in order to perceive all the warding spells that were permanently installed around the trading pit at the Carthinias Exchange. These suddenly became visible—though badly washed out by comet-light—around Reamde and his phalanx: at least a dozen concentric layers of colored force fields, some dome shaped, some conical, some open-topped cylinders, all depicted in different hues and shimmering with various textures. Spells for turning aside projectile weapons, for stopping magical fireballs, for making hidden characters visible, and for inflicting damage automatically on any foes who tried to penetrate to the center.
