Loose Ends:This is an issue, I know. Yes, it is true that by the end of a multi-year project I get very burned out, so the endings go quickly.
But there are other factors at play here too, besides just me burning out.
I am a fan of martial arts films, Hong Kong cinema, and these movies generally end very abruptly, at least the older ones I love do - the hero/s finally beat the shit out of the Big Bad, there is like one second of them going 'YEAH!' slam to black, roll credits. This is very dramatic to me.
To me, the loose ends are all tied up, because they are clearly implied. In the martial arts movie, everyone left alive lives happily ever after. It's obvious that the wiry guy with the Monkey Fist will go back to his noodle shop, and that the Iron Leg Sage will go back to his monastery. It's what they would do.
By the same token, it just seems obvious to me, at least, what has already happened by the time we get to see Helio +100,000. Clearly they have brought Hannya and Ransei back, and installed them in new bodies, and have been hanging out with them on and off for centuries. We can automatically assume that Chartreuse would have been rescued, and every effort made to make her finally happy, because what happened to her is easily Heliotrope's greatest regret. It affected a lot of her actions throughout the story. We know Heliotrope's character, and we can be certain that with such power to rescue the long dead, she would use it to take care of those things that haunt her, like Chartreuse. I mean, wouldn't you?
We can further assume, quite reasonably, that with the compassion of Fuschia guiding the program, that there was almost certainly some process put in place, almost certainly a job forced on the MinYan as atonement, to rescue countless others, perhaps even everyone, everywhere, that ever lived.
As for Ktlikitkaktl; with energy more than sufficient, and with nothing but empty room, it would be easy to imagine that K'Chk would end up playing host to countless revived beings, and Ktlikitkaktl would become a garden spot of the multiverse, once it thawed completely out, and became all green and lovely. We can imagine K'Chk becoming the gracious host of the most marvelous vacation spot in the metacosmos... and likely the first awakening place for newly-revived beings. As for Meiun, I would suspect he would probably want to go exploring... out there.
By showing the lives of our core group millennia in the future, automatically I assume the reader understands that Fuschia and Heliotrope actually did what they agreed to do while they were falling, and that in the act of still caring about birthdays and family, their character had not deeply changed, and that compassion must have guided how they dealt with the power of resurrection in those ages past.
I guess I assume the reader, like me, would just naturally set up a system to save everyone, if they could, and had eternity anyway. Why not? It's kind and generous and compassionate.
For me, knowing the hearts of the characters by their actions, all the loose ends are tied up. If it is loving and heroic, Fuschia and Heliotrope will do it, and Ran and Hannya will likely be involved, one way or another. That's who they are. For me, the rest is detail, food for fanfics and daydreaming. The core of the story completed, there is something left for the reader to imagine beyond the story for themselves.
Maybe that is not the best for everyone. I can understand that. I like that sort of ending - which I get a great deal of in foreign films of all kinds, not just martial arts movies. I've seen this sort of thing in French animation, Japanese animation, films from Europe, and from the Pacific Rim. The core issue is resolved, big hurrah, but the details of the lives of the characters afterwards are left to speculation, based on having gotten to know them. I rather like that delicious flavor, and some things I've seen, or read, have left me delightfully pondering 'what happened next' for weeks.
So there is burnout, yes. But there is also what I have tried to describe above as well. Both influence my endings, I am beginning to learn. This is, after all, only my third completed epic comic in my entire life (I'm including Cosmochronicles,
http://unicornjelly.com/cosmocover.htm because, hey, it is an epic story, even if it was done when I was only 11-ish).
