Once your message is relayed, the Imperials call off their attack on Erengard! Transports are sent to retrieve the AT-ATs that were marching across the golden fields below Maurenburg. The Imperials suffered no casaulties out that way, while you lost all of your men in your ambush of the Palace of the Castellan. They will be given full military burial on Coruscant.
Unlike you. You survived and are now disgraced on Erengard. Tarkin agrees full-heartedly to the terms that your father sets. You are never to return to Erengard under pain of death. Einar makes it quite clear that he intends to uphold this as long as he lives.
A shuttle comes to retrieve you from Maurenburg. Grand Moff Tarkin himself steps off and beckons you aboard, flanked by a squad of white-armored stormtroopers.
"Remember what I said about Alderaan," the Castellan says to you as you are turned over into the custody of the Empire.
"This could have gone better, Melkor," Tarkin scolds. "You have much to learn about the way of politics and power in the Galaxy. I see much promise in you. Perhaps now that you ties to your homeworld are severed, you will be more focused and serve the Empire and the Empire only."
