Darth Vader

The Imperial Palace, built on
Coruscant as the headquarters of the Emperor, is taller than any other
structure on the planet including the neighboring Senate building and
the imposing Jedi Temple. The Palace is said to be an impregnable
fortress, with some areas decorated by Palpatine with patterns based
on ancient Sith hieroglyphics."

For a time, the Emperor believed that nothing could seriously threaten
his rule: his old enemy, Mon Mothma, was clever and strong, and the
Rebel Alliance was growing, but without the Force, neither could ever
become a serious threat. In some ways, the Rebellion was a useful
scapegoat, giving him an excuse to further undermine and corrupt the
Old Republic's justice under the pretense of an emergency state of
martial law. Soon he would not need them any more, and in the fullness
of time, they would be attended to. All was right with the galaxy and the
New Order was unstoppable.

But the Emperor has become aware of a new current in the
ever-flowing energy of the Force. It began as a subtle, barely perceptible
surge, but in a short time has grown into the bright light that he now
knows as Luke Skywalker. Lord Vader observed to his Emperor that if
Skywalker could be turned to the dark side of the Force, "he would
become a powerful ally." And so the Emperor plots to deal with this
young Skywalker: he will join the New Order, or he will die. Pitting Vader
against Skywalker, with all their psychological threats for each other, is
all part of the Emperor's plan, and he remains evilly confident that no
matter who is killed, he will settle the balance of the Force to his
satisfaction.
