I too was unsure about using the term Legate in the opening crawl. It's an unfamiliar (but real) word to most viewers, maybe Ambassador might be a better choice? The idea is that Marya is the sister of King Bail Organa, the ruling monarch of Alderaan. She is not in line for the throne, but she does serve in the capacity of a liaison with the Galactic Republic. I very specifically did not want her to be a Republic Senator in this verse because...well, does the United Kingdom have a Senator in the United States Senate?

No, of course not. Nor does the US have a Lord in the UK's House of Lords.

As for the dissident thing, I'll try to brush up the opening crawl to make it more clear the Obi-Wan and Marya are among the dissidents which escaped the planet.

Regarding the poetry parallels, I actually looked up the opening crawl from ANH (I must admit, I do not know it from memory!) and changed the clauses to fit my vision of a Clone invasion of the Core Worlds. Luke's presence was not indicated from the start of the film, and likewise neither will Anakin's. I'm intending for Anakin to appear on-screen at roughly the same minute mark as Luke did, but in the seedy world-city of Nar Shaddaa instead of the warm Lars homestead.

Also, I read of the three-planet pattern in the OT and how that got jumbled up in Episodes II and III of the Lucas prequels, so I'm going to try my absolute BEST to keep the number of worlds visited in each of my prequels to exactly three. In this film I'm intending for the three worlds to be Kuat, then Nar Shaddaa, and finally a return to Clone-occupied Alderaan for the film's climax.
