Which is to say you just use a save editor or cheats to temporarily give yourself some dark side points at lvl 15 then switch back after you prestige, lol. It is a solitary path that exists beyond the corruption of the Dark Side and the weakness of the Jedi Order. A true Bright Lord of the Sith must be able to alter the very fabric of reality itself, to bend the Force to their will to serve the greater purpose of all.
