Darth Sidious

It's from the office of Chancellor Palpatine—no, Sidious now.

"Lord Vader. Go to the Mustafar system. Wipe out Viceroy Gunray and the other Separatist leaders. Once more, the Sith will rule the galaxy, and then...we shall have peace," your new master says sinisterly.

"Yes my Master," you reply. Shutting off your comlink, you step back into Padme's bedchamber. You take your pregnant wife into your arms. She looks up into your eyes. "Everything will soon be set right Padme. The Chancellor has given me a very important mission. The Separatists have gathered in the Mustafar system. I'm going there to end this war. Wait for me until I return...things will be different, I promise."

You kiss her passionately one last time and stride out to your starfighter.
