Originally posted by ZenwolfYes I meant at 0:09, we see Vader enter what appears to be a section of the Sith planet/temple before the Inquisitors. We then later see the Inquisitors & Vader fighting the protags also on the planet.
That looked very vision like, the way he appeared seemed to show him as some kind of god in that instance, standing on his TIE, the rays of light behind him. Plus even then, look where Ashoka is? She's meditating in what appears to be a dark side place, she hears Vader's/Anakin's voice, the red mist surrounding him, which then goes into a fight apparently.
Its likely Ahsoka experienced a vision of Vader and then Vader himself appeared later on.
EDIT: Also anyone notice the green lightining flash at 0:30? Very Malachor-esque.
