Genemaker

Genemakers were ancient devices used by the Rakatans to modify and, in some cases, create genetic material. With these devices, the Rakatans were able to create most of the humanoid species that inhabited the galaxy by precisely readjusting genetic material such as DNA. Some of these modifications went wrong, however, resulting in the creation of various mutant species that either died out quickly upon creation or developed into abhorrent beasts.
