I've done a bit of Googling, and I can't find any substantive information about it. From what I have read, this is set in the era of the -- cough cough -- High Republic (you can thank Kathleen Kennedy for that), which makes it somewhat well before the era of Luke, Leia, and Han. The trailer doesn't pony up much by way of story -- there are some Jedi and images of ships similar to those from The Phantom Menace -- and it looks to be there's an evil tar that takes human form and poses some dire existential threat to the galaxy's drum and bugle corps. mybe this is Naboo? It kinda/sorta looks like what I'd imagine a Naboo swap meet to be. There are also pirates and Cylon Raiders in it, if I'm not mistaken. Of course, who but the Jedi Council should be consulted in such circumstances? I think that one black fluid creature is the thing that killed Tasha Yar, too, so that can't be good. Hell, it ain't even the right franchise, a testament to Kathleen's 'guiding hand,' I'm sure.
In any event, I won't belabor the point. Those truly interested in knowing a bit more are gonna have to put in the leg work yourselves as this one looks interesting but isn't up my alley.
