The P'w'ecks are a brown-scaled saurian species native to Lwhekk. They are similar in appearance to the Ssi-ruuk, although their smaller size, drooping eyes, short tails, and lower intelligence clearly distinguish them as a different species.
The Ssi-ruuk have long dominated the P'w'ecks, enslaving them and controlling their breeding. Any spark of creativity and initiative has been bred out of the species. The Ssi-ruuk treat the P'w'ecks like work animals: useful but expendable.
When the P'w'ecks reach the equivalent of 15 standard years of age - just old enough to mate but prior to maturing as an adult - they are "enteched" (a process in which life essence is transferred into computers). P'w'ecks who are allowed to live to full adulthood become unstable and violent, and often injure themselves and those around them. They are genetically incompatible with the Ssi-ruuk.
P'w'ecks perform a number of menial tasks in Ssi-ruuvi society; they are servants, beasts of burden and guard creatures. They cannot be trusted, but the Ssi-ruuk use training, punishment, torture, and traps to force the smaller aliens to perform their duties. By relying on large crews of P'w'ecks, the Ssi-ruuk need to send only a few of their own kind into space. Enteched life energy from P'w'ecks is a vital energy source in Ssi-ruuvi civilization and by enteching these creatures as they reach adulthood, the Ssi-ruuk do not have to contend with stronger, smarter and more rebellious adult P'w'ecks. |
