What I found familar was it was similar to a few themes in other stories/movies.
Like Phantom of the Opera with Erik(The Phantom) and Christine.
or the political issues and empire feel of Star Wars
I don't want to be a tease, but it is NOT any of the ones we have been discussing.
Let's just say it fits both the thematic and literal intepretation of "V for Vendetta" IMO, and will be done in a few days... That's not so far away if you think about it
