The Codon Stream is the system of rivers of "green lava" that are spread throughout Primus. The stream originates in a volcano, which is actually the processing plant for the DNA of the stream. There are no non-sapient beings in the Codon Stream. Originally, there was thought to be 10,000 DNA samples in the Codon Stream . But A very smart scientist has revealed that there are samples from every sapient species of every world in the Milky Way Galaxy: over 1,000,000. As confirmed by A resercher. But that resercher found more resulting in a grand total of 1,000,910 samples, meaning there are 100,091 sets of aliens.
