I am a firm believer in rubbing serial numbers off. Also, given how wild some of my AUs get, taking a Hakoda/Ozai AU and making it into an original universe isn't all that hard.

This is just a completely raw story-dump, though. Just getting the opening sequence out of my head without trying to be very pretty about it. Which means a fair amount of the info-dumps are awkward, there's not much description, and the science is just barely fact-checked.
