Primus (Earth-103)/DImension 1-2

Primus is the DNA "back-up" drive for the entire Milky Way and Andromeda Galaxies.

History
Even though Ben's Omnitrix isn't hooked up to it anymore. It still remains active. Azmuth actively has new DNA added, even non-sentient creatures and flora. It is still online, just incase the Omnitrix loses DNA and needs a back-up for it.

Geography
Primus has three main rivers: One for sentient creatures; the Codon Stream, one for non-sentient creatures, and one for flora. There are also settlements with robots that categorize DNA into their respective rivers.
