Charles Soule, the author of The Light of the Jedi, confirmed in a tweet that the Amaxine station from The High Republic: Into the Dark was featured in his Rise of Kylo Ren mini-series.
Interestingly, the aforementioned location ultimately became Supreme Leader Snoke’s space station during the sequel trilogy. This is also where Ben Solo met Snoke after destroying Luke Skywalker’s Jedi Temple.
For context, the Amaxines were a group of ancient warriors that originated from the dawn of the Galactic Republic. The Amaxine warriors had a unique barter system that involved trading weapons for goods and services.
At some point during their existence, it was believed that they left the galaxy to search for another one since the Old Republic was deemed too powerful for them to conquer. The life of the warriors will be chronicled in Into the Dark when it releases in February 2021.
This is a prime example of the interconnected nature of the Star Wars franchise. The connection to Snoke seemingly implies that the High Republic stories are poised to not just offer clues about the prequel trilogy of the Skywalker Saga, but also lay the groundwork for the much-talked-about sequel trilogy.
When Snoke first appeared during Star Wars: The Force Awakens, many assumed that he would end up as the big bad of the sequels, but his untimely death during The Last Jedi proved otherwise. Instead, the villain was placed on the sidelines to elevate Kylo Ren even more while also being used as a plot device to explain the sudden revival of Emperor Palpatine during The Rise of Skywalker.
