In the Expanded Universe, Jabiim was one of many planets the Republic went to war on. Now, it's set to be added to the current continuity in Obi-Wan Kenobi, with O'Shea Jackson playing one of the Partisans who, we know, are aligned with one Saw Garrera. It's still early days for the group (and no, Jackson isn't playing a younger version of Forest Whittaker's military hero).
According to Making Star Wars, these Partisan fighters are using blasters and weaponry from the Clone Wars, something that understandably brings back memories for Obi-Wan. After previously fighting on the planet, the Jedi Master learns that Jabiim is still in the midst of war, albeit with these fanatic Rebels now using the Republic's weapons to fight back against the Empire.
If we had to hazard a guess, this will be where we get a live-action flashback to The Clone Wars.
We'll have to wait and see on that point, but we know from Rogue One: A Star Wars Story that this group of Partisans one day becomes radicalised, paranoid, and heartless in their approach to fighting. This group is made up of those who can fight and those who can't, and the site posits that we'll see some join Bail Organa's Rebel Alliance, while others head down a darker route with Saw.
There's no word if we'll get to see some familiar faces from Rogue One, but for hardcore fans of the Star Wars franchise, it's clearly the plan to flesh out some elements of that movie and this Galaxy Far, Far Away. That's exciting on a number of levels, and at least a handful of cameos seem somewhat likely.
After all, Lucasfilm is fleshing out this period between Revenge of the Sith and A New Hope in a lot of different stories right now, and it only makes sense for them to begin crossing over.
