You want my take on this?

Consider why those Temples were largely abandoned. My suspicion is that it's related to the Yoma Sorcerers waaaay back during the Purge--I would not be suprised if the new Sorcerers simply learned how to re-activate the long-dormant "anti-Jedi" mechanism like they did back then.

It's the Purge all over again, but there's one thing against it: Vader is on the other side this time. That's quite likely part of the reasoning behind the "fulcrum," IMO--Len and Emmy will play their share, I know.

Other than that, I don't care if it's light on the fighting--a good mystery is also very enjoyable. Can't wait to see the last installment!

(Note: I orignally envisioned the Grushkans as Minya-shaped, but with backward legs. Comes from moderating an active Godzilla forum, I guess.)
