They entered the Renraku complex into a backwater slave module that was overseer for a bank of elevators. Such a node should not have allowed access to the system but it was, after all, a back door. The appearance was that of a small guardroom. Its smooth walls flashed infrequently with light as the elevators went about their business. A samurai dozed in one corner of the imaginary room, his neon armor dull. Because the elevators only connected a small spread of floors in areas of minimum security, the guardian ice would normally be activated only in an alert.
