Only add stuff about Star Wars, mainly, the Jedi Rebellion against the Sith Empire. So basically anything from A New Hope (Episode IV),
The Empire Strikes Back (Episode V),
Or Return of the Jedi
Darth Vader, Luke Skywalker, AT-AT Walkers, AT-ST Walkers, C-3PO, R2D2, Yoda, Han Solo,
Millennium Falcon, Darth Sidious,
Princess Leia, The Death Star,
The Death Star 2. Pretty much anything from the original Star Wars Trilogy. You can add anything Star Wars related, but I think the Rebellion was only in the original trilogy.
