Thursday morning was a monumental time for Star Wars fans around the world. The first teaser trailer for "Rogue One: A Star Wars Story" dropped, and fans exploded into a frenzy. Though this isn't the much-anticipated Episode VIII, fans are excited to venture into and explore elements of the expanded universe. The movie is set to for release on December 16, 2016. Even though the trailer was short (just under two minutes long), a lot was revealed in those couple of minutes.

1. It is set between Episodes III and IV.

Though it takes place closer to the Episode IV era. The plot follows a group of rebels who are given the mission of stealing the plans for the Death Star from the Galactic Empire. Fun fact: The rebel group and their mission is actually referenced in the scroll at the beginning of Episode IV (Star Wars Wiki)!

2. Jyn Erso is the newest main character.

Jyn is the leader of the Rebel Alliance team tasked with stealing the plans for the Death Star. She has been on her own since she was 15 and has developed quite the criminal record. Some are speculating that she could be Rey's mother from "The Force Awakens" (Wookieepedia)

3. Mon Mothma makes an appearance.

Mon Mothma is the only original Star Wars character to be seen in the teaser trailer. She was introduced in the prequel trilogy and is now acting as the leader of the Alliance to Restore the Republic. Because she is one of the original characters, fans are left to wonder if any other originals will make a cameo.

4. There are a bunch of new characters.

One of the coolest elements about "Rogue One" is all of the new characters that are being added to the expansive Star Wars universe. Though the original characters are beloved, these new characters bring a whole new storyline to life. There are so many possibilities for story creation because fans don't know much about these characters.

5. There is a rumor that Darth Vader will make an appearance.

According to IMDB, Darth Vader could make a cameo in "Rogue One." At the end of Episode III, fallen Jedi Anakin Skywalker dons the black armor and mask to become one of the most famous villains in movie history. Because "Rogue One" is set between Episode III and IV and focuses on the Death Star, a battle station that Vader is helping run, it only makes sense that he would be in the newest movie. Now the question is whether or not actor Hayden Christensen will reprise his role, and if James Earl Jones will provide the voice.
