For the sake of hopefully drawing others in, lets keep it on this thread, Kyle Ajahn Thanks for showing interest!
Premise: Whole groups of people have made their careers trying to figure out how to turn Force Adepts to the Dark Side. Be it seduction, conversion by torture, or alchemical sciences designed to twist both body and soul.
Long ago, some enterprising combination of scientists, the head researcher of which was trying to figure out how to turn his own wife back to the light sought the reverse. As he was no force user himself, he had only his science to aid him. His wife had been turned into a knight of ren, and he had barely escaped her search for him. He spent years paying bounty hunters to capture Dark Jedi for him, so he could study their brains behavior centers during active use of the Dark Side. The surgeries, brutal and illegal in the extreme, began soon after. He hoped that by altering the brain itself and how it processed emotion, he could drastically reduce the Brain's ability to tap the Dark Side, even if it desperately wanted to. He also made significant--and bloody--efforts to discover whether sheer brute intimidation and torture could force a dark sider to give up the Dark Side. He never did find that magical fix that would deliver his wife back to the light, and he reluctantly killed her himself in the end, but his research was preserved in old computers deep within the site. But the pain he inflicted on his subjects has left its mark in the form of strong imprints in the force that are riddled with pain, as well as security systems designed specifically to capture other force users. If the nice guys want to know any insight the scientist gained, even if only to keep it from the hands of their enemies, they have to run the gauntlet of a highly secure, deadly, and abandoned underground...with a crazy bounty hunter interested in the research for her own ongoing issues.
