The following contains spoilers for Solo: A Star Wars Story.
While we expect to find a lot of easter eggs and references in franchises like the Marvel Cinematic Universe or the next Pixar movie, it's not something we associate with Star Wars, and yet, Solo: A Star Wars Story was full of them, some quite obscure. If you knew what you were looking for you may have noticed them, but like any good easter egg, these probably flew right be anybody for whom they meant nothing.
Of course, for those that did catch them, these were some great references to elements of Star Wars fans had assumed had been long forgotten. However, it seems that screenwriters Jonathan and Lawrence Kasdan, along with the rest of the filmmakers, hadn't forgotten these parts of the galaxy far, far away after all. Here are a few of the more deep-dives into the Star Wars universe you may have missed.
The Black Spires
One of the most obscure references in Solo was hard to catch not because it dealt with something old and forgotten, but because it dealt with something so new that most people aren't familiar with it yet. After Han and Qi'ra successfully enlist the help of Lando Calrissian, and the crew are headed off to Lando's ship, we continue to get to know Lando's co-pilot, the droid L3-37. At one point, as part of showing off her navigational knowledge, and Lando's lack of the same, L3 says that Lando couldn't even find The Black Spires without her.
The Black Spires exist on the planet Batuu, a place nobody has really seen in the Star Wars universe yet because it's the world that will be the home of Star Wars Galaxy's Edge, the new land set to open at Disneyland and Walt Disney World in 2019. The Black Spires themselves have been referenced as part of the promotion of the land done via a set of collectible cards, and they're visible in the image above which was released along with the most recent announcement regarding when the new lands will open.. They're geographic landmarks on the planet that lend their name to other locations, like Black Spire Station, but beyond that, we'll have to wait and see what else, if anything, they may mean.
