In a StarWars fanfiction this troper has been writing, the centerpiece is a Sith artifact that is one part SoulJar, one part {{Magitek}} nuke, and one part {{TheVirus}}. It can (temporarily) raise the dead, destroy stuff with blasts of Force energy, manipulate nature, and destroy armies. But it needs a host and '''it will find one'''. If it is safely encountered, be very afraid. It wants to be found, and the spirit inside of it, the soul of a Sith Lord, wants a Jedi host. Fourteen separate Jedi Masters were strong enough not to fall prey to it, but could never destroy it (one even tried to send it down a black hole -
didn't work),
only seal it away. Anyone unfortunate enough to fall prey to it is subjected to MoreThanMindControl, so his or her allies aren't really sure, at the end, whether the shit he spouts is his own or the artifact's, and because it slowly worms its way into the victim's mind, the GenreSavvy allies are
never quite sure when they will turn. This becomes really important because the heroes are KnightTemplar ex-Jedi fighting for their lives against an onslaught of Sith troops during the
Legacy era. Any one of them would be a perfect target.
