It just strikes me as odd when Vader is not the only active DS force user working for the Empire, as late as 5-4 bby the Inquisitorius was working with other Imperial outfits to fight the Rebels.

And even before the PT happened, when I had only seen the OT, it always struck me as odd that any Imperial would have the gall to speak to Vader, who I presumed was known to be the Emperor’s second, so brazenly. I know a lot of things changed behind the scenes from Star Wars to ESB, but this has always irked me.
