Darth Bane -vs- Luke Skywalker
Darth Bane, during the beginning of Dynasty of Evil, is whisked away by the Force to Dromund Kaas.
Bane, upon wandering into the Dark Temple, immerses himself in the Dark Force energies there, meditating on them.
Elsewhere, the current incarnation of Luke Skywalker is whisked away by the Force and arrives on Dromund Kaas, at the entrance of the Temple.
He walks in, and Bane turns around from his kneeling position.
He arises, and the two face each other.
Without a word, there is a hiss-snap as Bane lights his saber.
Luke realizes this is a Sith Lord, but does not know who he is.
He wants to defeat this Sith Lord, but in typical character, he doesn't want to give into the Dark side by killing him.
Bane of the Sith recognizes before him, a powerful Jedi Master - he doesn't want to hold back, and will indeed kill Luke if he can.
The two take deep stances, and prepare to hurl themselves at one another.
