In the first century of his life, Dax was part of a R&D team for experimental techknowledgies. While working on a new explosive device, his work was sabotaged and it went active and killed 4 members of the team, injured two others not including himself. In that explosion he lost both his right arm and leg and shrapnel hit his eyes damaging them some. Doctors and technitians worked for 6 hours on him using research that they found in his archived data records before the connections were completed for the prosthetic limbs. The implants in the eyes were the first to go in to keep him from going completely blind. Now with the implants he has zoomable vision as well as a small amount of x-ray capabilities. Also via his neural implants he can output and record exactly what he sees.

In the next two years Dax himself developed and installed his own cybernetic limbs which he still works on and upgrades from time to time, all the while making them look more and more like his real limbs but with certain advantageous capabilites. With his new limbs he has been able to continue his work, but now in his own personal lab since he is retired from his official position.

Since then he does commision work for the highest bidder. Reverse engineering, conceptual construction, and other upon order electronics... legal and not so... legal alike.
