for the government to add one more measure of control to the everyday lives of the peoples of Thel. Computational machines were advanced enough in Thel that certain facilities were maintained and monitored by artificial intelligences that substituted for human control when humans were busy with other concerns. For example, the Sarlicon brain was an ancient but artificially intelligent computer tasked with the safekeeping of the memories of the android population of Sarlax. The computer was subject to humans with high level access crystal keys but could defend itself from human attempts to circumvent the machine's operations. In Thel there also existed robot technology that allowed android design including androids so advanced they were indistinguishable from flesh and blood humans. These advanced androids are known as "Plasmoids" and they occupy the province of Sarlax serving as miners that can tolerate the minerals' radiation. Access crystals were the method of securing high level databanks, travel, power sources and other high security areas of Thel. The crystal was basically a faceted glass appliance, several centimeters long, purplish in color, with a series of electronic chips and components inside. They are individually numbered and have the "mark of Imar" engraved on the bottom. Though not fully discussed in the series, it might have operated by being optically read or perhaps the electronics were of an RFID type. The crystal was read by a reader that simply allowed insertion of the crystal less than halfway into its interface shaft. A light would illuminate the crystal as it was being accessed and most readers were shown tied to computer terminals but in some cases they were freestanding units not unlike keyholes and used to secure doors. It was mentioned in the pilot that Kroll possessed a "class 1" access crystal, which is possibly the highest access class. What the lower class crystals' abilities were was never revealed. It was mentioned in the episode "Metraplex" that advanced electronic entertainments known as "wave games" and "gratification intensifiers" existed. How these devices functioned was never revealed but it was also mentioned in the same episode that the province also produced "particle beam" weaponry had access to a "disintegration chamber" and subjugated an entire underclass population with "Vibratory Behavior Modification Modules". In another episode, weapons called "electrum bolts" are mentioned; they are supposedly deadly and exotic in what they do to living tissue. The state soldiers, the Zone Troopers,
