Shooting Star ran back to the palace quickly hiding her wings with her magic. As soon as she got to the palace she found Princess Celestia in the throne room crying, the elements of harmony lying on the floor around her. "Princess Celestia, are you okay? What happened?" she asked with fake concern for her.
Turning around to see who disturbed her Celestia noticed Luna's Captain. More shame and guilt washed over her knowing she had to tell Shooting Star. "I will be okay Captain. Thank you for asking. However, I can not say the same for Luna. She attacked me, started claiming that she was Nightmare Moon the empress of Equestria and that night would last forever. I couldn't reason with her and had to use the elements. She has been banished to the moon. I'm Sorry." By the end Celestia was crying so hard she never noticed Star leaving.
Knowing that she was now in charge of the thestrals, Star gathered all of Luna's night guard in a secluded part of the castle. "Thank you all for gathering so quickly. I have important news I must share with all of you." The ponies before her began to quietly murmur, curious as to what would require all of them. "The most important thing that you need to know is that Princess Luna has been banished to the moon." Many of the guards started to panic not knowing what would happen to them now that their protector was gone. "Please Let me finish. I know this is difficult news to take in however you must pull yourselves together for the sake of your brothers and your families. We are going to take the confusion of these events and use them to benefit our efforts to leave. Princess Luna has left me in charge of your safety. I want to get every thestral in this city out before tomorrow. "
"Captain what are we going to do? Is there anywhere we can go?" Many guards spoke out.
"I want us to go back to our city from before Luna found us. Its outside of Equestria so we won't have to worry about Celestia. I want a team to head there immediately after this meeting to get things ready for the rest of the guards and the civilians. I also need a team to escort the civilians there. Everypony else you need to gather what you need and head out in the next 20 minutes, stay in groups as you make your way there."
After giving the group, heading to the town, packs and teleporting them as far as possible, Star went to help the thestrals staying to get their families out. Setting them up a little way into the forest. Then she went out to tell the thestrals in the city. At every house she stopped at she told the families to pack only what they needed and that they were to leave an hour after sunset.
Once everything was done she headed back to the palace. Star stopped at her room to get the few things she needed before heading to Luna's room. When Star got there she was surprised to find a letter and a package with her name on it. Star continued to search the room for anything else Luna would need when she returned.
