The Inquisitor and the Empire

It's a question of why didn't we see these guys in the original trilogy? I mean, the Inquisitor surely would have been active at some point during that time. Maybe it's their exploration for Ezra going into the Unknown Regions or messing around with the world between worlds. And now you have mercenary Jedi and Inquisitors and all of this stuff going on. This setting, this sort of dark forest setting that we're looking at here does remind me a little bit of the forest that she first encounters Grogu.
