Honestly, I figured you'd do the entire Destiny 1 game, then go to the Hive attacking the Citadel species.
Of course, the Red War will be hard to take into account.
Note: Sorry about that, questions are still open I'm just hard at work with the new project along with some important real life stuff.
That was actually the original plan. We'd go through vanilla Destiny with some alterations to the Black Garden/Vault of Glass (Tali's development regarding AI would have been tied into The Last Array), then Dark Below. House of Wolves would have been interesting because the hunt for Skolas wouldn't have been in
this story, it would have been the second story arc of the Fireteam RWBY idea that I considered before scrapping it (which also would contain the Venus' Fallen arc in vanilla Destiny) but there would have been a full arc involving Taniks the Scarred. Then we would have gone into Taken King then head into the Hive War arc.
The thing is I realized that would make a shitty crossover.
See in my opinion, the fun of crossovers (in particular the fusions I adore) is exploring either the changes caused by two different setting colliding or the various culture shocks, alien points of view, and all the changes in characters and worldbuilding that comes from that. And most of the Destiny 1 story arcs would have just been...Destiny 1 with ME characters. Now there would have been that storyline of the Citadel members of the cast getting used to the City but eventually they'd just adapt. Like Fry in Futurama, this strange environment would have become home and then its just normal.
Now, don't get me wrong, a Destiny 1 novelization with better plot structure, worldbuilding, and actual characters (preferably some kind of ensemble) would be super fun and I hope somebody writes it someday. But it wasn't what I wanted to write and it wasn't the product I was advertising. Besides this was when the uncertainty about the future of the fic was starting to set in and if the plan I revealed in the final post was going to take the better part of 10 years to finish then the original plan would have taken the better part of
20. I seriously sliced out 6-8 books when I sliced out all the Destiny 1 stuff.
Now, someday I might put up a quick summary post about what I had planned for D1 books but for now just know that I sliced it out (except for very key flashbacks involving King's Fall and The Last Array) for good reasons.
