^ Let me guess: Does this toy happen to belong to an overly litigious old dwarf whom we shall nickname "Grouchy"?
Different set of toys. The Larry Niven toys.
"The Slaver Weapon" tells us nothing about the Slaver Wars, only that they happened billions of years ago. In Known Space, we know that the Tnuctip only defeated the Slavers because they created the "Scream," an immensely powerful weapon that caused every sentient creature in the galaxy to commit suicide. We don't know how the Slaver Wars ended in the
Star Trek universe, though. What if there were no Tnuctip in the
Star Trek universe? What if the rebellion against the Slavers took a different route...?
Consider what assimilation does. It takes a biological machine and slaves it to a silicon machine, overriding the biological nervous system with a mechanical nervous system.
In a war against the Slavers, who were immensely powerful telepaths, something like the Borg would be the ultimate weapon. The assimilation process would override the nervous system that the Slavers tap into, and it would turn a soldier for the Slaver armies into a soldier fighting against the Slavers.
The Borg make perfect sense as a weapon against the Slavers. Unfortunately, once you've turned a weapon like that on, it's impossible to turn off, and thus the Borg continued to exist. And this lead into other things, like why the tech state of the galaxy seems to be uniform (the Borg will go through and assimilate the galaxy, basically sterilizing it, and with nothing left to assimilate they retreat into hibernation, the life process starts again, and this could repeat itself every few million years or so).
That was my theory, anyway.
