The fifth variant beast rider neural interface. In his fifth design, Ves chose not to do anything crazy.

Sitting in between the first and second variant, theoretically it had the highest chance of success!
"Prepare the seventeenth dwarf captive."
Eleven out of sixteen dwarf captives already sacrificed their lives for science today.
If these experiments happened in civilized space, the MTA would have already shut it down and investigate his scientific rigor.
The main reason why so many dwarves died was because he only vaguely knew what he was doing. He understood so little in the field of neural interface technology, yet progressed immediately to live testing. Such a decision was irresponsible to the extreme.
