Over the past year I've had actually quite a few requests to post a summary of the ending events. So here it is! Special thanks go to Meneldur who managed to get me to finally do this.
I could not find my original notes and outline, so this was all done from memory. The story is accurate (it's hard to forget your own story when you have it planned) but there are details and plot points missing. If you have any questions feel free to ask in a review or message.
I guess in total this accounts for an additional 12 chapters to RevEl and, if completed, would make the story roughly 200,000 words.
Ending Summary
Usagi's party makes it to Genum Ku'gnae and Titan (Saturn's shrine) after running through all sorts of problems. They had quite a bit of distance to cover and so the journey was rather substantial. Along the way, Llematai finds them and after some lovely mental and physical torture for our heroines (resulting in much angst of course) they regroup and defeat her-Rei specifically kills her. There is some relationship stuff that develops over the journey too. Makoto and Ami continuing being cute because damnit, there needed to be at least one sane, stable couple. Rei however, who just can't help herself any longer, despite recent distractions in the form of Minako, makes a move on Usagi. Cue Minako angst. Usagi reciprocates for a short time, and then, after separate talks with Setsuna and Hotaru realizes Mamoru is still her one and only. Cue Rei angst as she realizes Usagi's decision without even needing to be told and she beats herself up over "forcing" herself onto the princess and making her make that decision. Minako is there to pick up the pieces and by the time they reach Genum Ku'gnae, Rei and Minako are inching closer to something more than friendship. We also learn from Setsuna that Rei, when she killed Llematai, accessed a higher order of magic, formally making her an immortal-like being like the Outers. After this, her magic is no longer twisty and dark, which had been a problem up to that point. Setsuna keeps the information to herself though.
Meanwhile, Haruka and Michiru are done with angst (for the moment) and are all about action. There is some relationship fluff and maturing, but more importantly, they are researching everything they can about Ochas. They officially find out that, not that they didn't suspect, that he's an occult nut who seems to be researching every manuscript and document that mentions magic, enchantment, and the supernatural in the palace library. They also worry because material on Saturn keeps popping up among his research materials. Talking about the displays of his magic that they've seen and the research he's performing, they know he has a fearsome collection of spells in his repertoire. During this time they are also sneakily going about helping the rebels under Mamoru (though they never actually meet and the rebels don't even know they are helping). Ochas increasingly spends more and more time in the library to the point of ignoring all else, and Haruka and Michiru conclude that he must be on the verge of finding something thus they hypothesize that he's after something specific in the library. They discover that Ochas had not only visited Pluto's shrine, but also Saturn's shrine a number of years ago. Then one day he appears with the Garnet Orb, disturbingly gleeful. He gloats that he's found everything he needs to get Saturn. He grabs them and off they go to Genum Ku'gnae.
Usagi's party arrives at Titan. Hotaru's acting quite strange, and in the center of the shrine, they find a girl that looks exactly like her who holds a glaive. As the others talk, Hotaru approaches this physical twin and touches her. There is a deep purple light that engulfs the whole area and once that fades, Hotaru and the other girl are completely gone. As Usagi and the others begin to panic, Ochas shows up with Haruka and Michiru. Setsuna takes a look at Haruka and Michiru and is basically like "oh shit," while Ochas is all "muahahaha," throws some summoned demons of some sorts to occupy them, and then ignores them as he approaches the center of the shrine. He does some magic on Haruka, Michiru, and the Garnet Orb. Setsuna freaks out (as much as she can freak out anyway) and Haruka and Michiru are also compelled to pull out their talismans. Then there is a light show and Hotaru/Saturn appears comatose where she had just disappeared. Ochas gets Haruka and Michiru to attack Usagi's party along with his summoned demons and he begins to work some arcane spell on Hotaru/Saturn.
Meanwhile, Usagi focuses on some crazy magic of her own while her friends are battling out with Haruka, Michiru, and the conjured demons. They are especially trying to do everything they can to try to interrupt Ochas, but its just too much power on Ochas's side (even with Haruka and Michiru doing everything they can to resist Ochas's compulsion). As Ochas is on the verge of completing his spell on Saturn and her friends on the verge of defeat, Usagi pulls off a miracle and complete undoes Ochas's compulsion on Haruka and Michiru. She collapses afterwards, but with Haruka and Michiru's help they begin to make some progress defeating the demons. It's too late however as with a flash of purple light, Saturn opens her eyes. With Usagi out of commission, the others decide to retreat when they realize they're facing demons, Ochas, and a mind-wiped, controlled Saturn.
Amidst all of this, Ami specifically starts freaking out because all of what she knows about magic is just increasingly blowing up in her face. This begins her ascent with her magic (that Rei already took) that puts her on the same level as the Outers. Makoto takes this journey with her and it later becomes the catalyst for her own evolution. For Ami, once she deals with it emotionally, she figures it out intellectually without needing some sort of crazy fight to access her optimum level of magic. Setsuna notes the change in Ami and keeps it to herself.
Ochas is on a power high after successfully obtaining Saturn so he lets Usagi's party go, deciding he didn't want to waste the effort that would go into finding them in the desert. Basically he thinks now with Saturn under his wing, he doesn't need to worry about them. Later, he does regret that he doesn't have Haruka and Michiru around to toy with anymore and he also wonders if maybe he should have gone ahead and chased after them that way he wouldn't even have to think about Usagi anymore.
After this point, there is an interlude with Mamoru, Luna, and Artemis that basically just checks up on them. We see that their rebel forces have become very well organized and are continuously growing-enough so that they are in contact with rebels outside the city too.
Usagi's party regroups at a desert coastal city a couple of days away from the shrine. Haruka and Michiru tell their story and what they know of Ochas and his actions. Setsuna believes that when Ochas, as a young man impatient for power, visited Titan years ago (learned from Haruka and Michiru) he attempted some form of magic that would forcefully awaken Saturn. Though Ochas failed at the time, Setsuna hypothesizes that his spell went completely wrong and split Saturn into two beings or that the spell worked, but gave Saturn a chance to set off a defense mechanism where she cast out her human form and left a corporeal, but spiritual self still within the shrine to prevent the binding. In any case, Hotaru's lack of parentage is the result of being the human form that Saturn was originally, a split caused by Ochas's impatient attempt to grab more power.
Things are not immediately great among the group as they argue about what to do even though they all realize its obvious they need to attack the castle. Additionally, Setsuna decides that Usagi needs some training so she's able to do magic more often then when she's just desperate. There is a whole chapter dedicated to group interactions that specifically covers initial clashing with Haruka and Michiru evolving to friendly cooperation.
They begin to travel back to Talrysc Kotyo, but it's quite a distance so it takes a while especially considering that they're dodging Arethian soldiers that everywhere. (I think I had decided it would take them a month and a half to get back to Talrysc Kotyo.) The closer they get to the capital, the more on edge everything is. Rumors are flying around the country that Ochas has been even more crazy than usual. During this particular journey, a number of things of note happen among the group. Ami reveals her powerup in magic, and tells the group that she's seen a spike in Rei's magic too (Setsuna remains silent on this issue). Makoto worries over Ami's intellectual obsession with it all. Minako can't just make that leap with Rei (despite Haruka's prodding) because she's worried that Rei is still in love with Usagi. Rei isn't sure at all what she's feeling. Usagi is worried over everything and everyone with no time to pine after anyone. Haruka and Michiru bond with the group, have a private giggle over all the relationship drama, and also firmly set the ship straight on their relationship with the kingdom and with each other (much sex is involved of course).
When they reach the outskirts of Talrysc Kotyo, Ami and Makoto venture out scouting and enter the city to find Mamoru, Luna, and Artemis. Makoto gets an upgrade in her magic when, during a random skirmish with some off-duty Arethian soldier thugs, she snaps and tells a super analytical tactical Ami (who has been thinking and planning the group's every move and dwelling on all the magic she's witnessed), who freaks out slightly at this unplanned event, that sometimes you just can't think on everything and you have to go in with passion. The skirmish ends just fine, and Ami's all about the passion that night (woohoo!). Anyway...plans made, they go back to the others.
I remember that the final few chapters that covered the climatic battle versus Ochas were left unplanned in my notes. But there are certain things I knew I had planned to happen. Setsuna gets her Garnet Orb back and proceeds to kick major butt. Rei and Minako get together when Minako rescues Rei after essentially saying screw it-fully accepting that love she owns regardless of Rei's own feelings causes Minako's evolution. Usagi, to everyone's horror, take a bad wound from Ochas just in time for Mamoru to see. Haruka and Michiru step in and fight Ochas, and somehow through sheer awesomeness (and maybe a little help from Setsuna) they break Ochas's hold on Saturn-explained through their familiarity with that particular magic. A free Hotaru heals Usagi and then Usagi, with Mamoru (rather uselessly) at her side takes down Ochas. During the fight, Ochas once again displays curiosity toward Mamoru. After a bit of verbal smackdown followed by a righteously physical one, Usagi wins. Ochas, his body twisted from his overuse of dark magic, disseminates into air disappearing as a negative Chaos.
RevEl ends with happily ever after for everyone of course. Setsuna and Ami get a lot of exposition. Usagi takes back her kingdom and rules as Serenity XII with Mamoru at her side. Countries that had been taken over by Areth reclaim their lands that had been lost under Ochas. Before the rulerless Areth loses its original territory to these other countries, it is revealed that Mamoru is a part of the royal Artehian bloodline and was spirited away to RevEl when Ochas began killing all those in between him and his throne years ago. Setsuna explains that not only did she originally advise Usagi's mother to appoint the Inner Senshi as guardians and companions, she finally tells them that have ascended to beings like the Outers (though Ami suspected). Usagi's special connection to the famous magic of her kingdom works the same way in granting her extreme long life. Usagi's queendom begins a golden age in RevEl with the Arethian territory coming under her control once she marries Mamoru. Additionally, Hotaru gets to have friends, Setsuna comes and goes as she pleases, and most importantly, Haruka and Michiru are free and able to enjoy the life together that they never had before.
