But it was the metahuman’s head that really startled Serrin. It wasn’t the cybereyes that were strange, but the filamentous network of fine, intermeshed metallic strands and what looked like monofilament optical fibers radiating out from them and flowing around the troll’s facial musculature and forehead. His mouth gleamed with metallic lips and his voice betrayed the existence of a fine voxsynth at work in his throat. The troll had no external ears, but concentric rings of carbonized steel and monofilament that suggested a level of chipping and cyberware that Serrin would never have dreamed existed.
