Cool that you enjoyed it.
As to your question, well there’s probably a multilayered answer to that depending on what you might have been looking from a personal perspective or maybe you weren’t looking for anything and were just wondering from a story lore standpoint.
Let’s go with story lore since that’s more important. Alright let’s get the main one out of the way.
Why is Francis so weak in all the ending?
Short answer is he’s ultimately mortal and will get old and die.
Which brings up, why doesn’t he just become immortal through magic? Well that’s a bit longer of an answer, so we’ll break it down.
So for just about every path, the concept of “immortality” isn’t really an option.
The whole normal soldier path is right out. (Beg in the beginning) He doesn’t have access to any magic and eventually gets old and dies. Doesn’t matter how good you are/were, old age is going to catch up with you as long as you’re mortal, which he is. The best he can do is make such a mark in the world that he becomes “Eternal” due to legacy.
That’s five of them down right there.
Moving on to the Shadow path (Die in the beginning)
As a shadow, he does have magic, but it’s not nearly enough to cheat death in any way. He’s only got the amount he does have due to Dendrin being amused by him and in one path he completely rejects Dendrin as any sort of god and the shadow religion in general. Though even in that one, along with the other two where he’s more dedicated to being a shadow, he basically merges with the shadow plane when he dies.
Now I left it vague on purpose, but in all three endings it does say he manifests as a being of pure shadow from time to time. His sheer force of willpower is at play in allowing this, so I’d say that’s a kind of immortality and not really weak even if he’s not really himself anymore.
Of course again, could just be a wishful idea from the shadows that look up to him as their “messiah” of sorts. Personally, that’s how I always saw it when I wrote it, but again readers can interpret how they wish since it’s all a make believe story anyway.
That’s those three down.
Moving on to the path everyone likes due to having a dark elf fetish (Struggle in the beginning)
So in this path he definitely has magic. Though if he ends up Buck Rogering himself into the future, he doesn’t ever really achieve his maximum potential (Never goes to Mortos). So again dies of old age, only achieves immortality through deeds.
That’s two out of the way. Three more to go.
Alright so in two of the paths, Decena lives through the battle with Mortimer/Zelvix which ends up changing events quite a bit. Francis ends up not being so focused on himself directly and due to certain events happening with her, he actually thinks about heirs and resolving the whole sterility thing.
So if he actually goes with that idea, he’s already discarded the idea of living forever in exchange of making the Eternal race live. He figures this his is immortality. Gets old and dies again.
That’s one out of the way.
The other one is becoming a brain in a jar, which means despite having someone in his life and such, he returns to placing goals for himself first.
Now in this one he definitely becomes immortal and I’d argue that he’s pretty powerful given that he’s still an Emperor and has been for hundreds of years. He could have continued this reign on a different planet with galaxy spanning empire if he wasn’t just tired of life at that point. (No Emperor of Man here)
Even if you mean he’s weak from a physical standpoint, he can just pop his brain into a battle mech and he’s definitely a threat on that front.
So now on to the last branch that leads to the potential Harbinger ending. This part will address the whole necromancy and magic thing.
So there aren’t any vampires around, so they don’t exist here. At least not in the traditional sense. (More on that in a bit) Liches do to a minor extent, but even then only on Mortos where necromancy is strong and all the necromancers there are just living a dull gray existence and they won’t really let anyone do anything more than that for fear of letting in the big bad Azrael in.
Necromancy doesn’t really work very well outside of Mortos and even then it only works by a powerful user of it like Casimir. Casimir has extended his life longer than most, but it isn’t working anymore hence why he came up with the whole Eternal project in the first place.
Besides necromancy not working very well, magic in general is on the decline in the world of Eternal. (As you pointed out in one of your posts) That’s mentioned on more than one occasion. There aren’t many powerful wizards around at the start of the story and usually regardless of which path that gets taken, wizards are in shorter supply. All of which means necromancy (extending your life unnaturally) is even weaker.
Only in this path does Francis get the abilities of a necromancer and by the time he does, he’s trying to accomplish what Casimir never did and he’s obsessed to the point where he’s not looking for half assed measures like life force draining people to keep himself alive like a semi-vampire. (That doesn’t work very well either since he’s gotta keep doing it more frequently and with more people just to sustain himself at the bare minimum.)
And of course as we all know when he tries to do what Casimir did and actually succeed, he fucks the entire world and that’s why it’s dead now.
But yeah, if he becomes the Harbinger, he definitely becomes a powerful immortal, but its at a pretty high cost. Nothing’s free.
So that’s the answer from a story lore standpoint
Now if you were asking for another reason like you wanted to become a god emperor that has 72,000 waifus (one for each 1000 years before repeating yourself) well that’s not what I wrote. Lol.
I just had the concept of a “womb to the tomb” story and wanted to write from the perspective of a villain protagonist. That’s literally it. While there was some planning and outlines, a lot of other stuff just fell into place a little later.
Ascending to godhood would have just been repeating Necromancer and while I do like repeating certain story ideas, I don’t want to repeat them so much that it’s practically the same story just with slightly different paint. Plus I couldn’t very well have godhood ascension in all the major endings anyway.
Also too, there is the idea that Francis’ life is a “mistake” anyway. He was never supposed to be in the Eternal project. He doesn’t usually get immortality since he wasn’t even supposed to get as far as he did in the first place. Whereas with Azrael from Necromancer it was sort of hinted at that he was sort of destined for his fate. He’s more of an example of a “Chosen One” though again I just did it from a villain protagonist point of view and that story was an attempt at what I ultimately accomplished in Eternal.
Still, I stuck with the title “Eternal” so that in every major ending he leaves a lasting legacy of some kind despite dying. Except of course for the one where he actually becomes immortal since in that one his world dies, so there is no lasting legacy. It’s just him as an immortal killing machine.
Anyway, that’s the basic answer for potentially “Why did you write this in this way” I guess. I never thought of him as being particularly weak even in most of the endings though. He’s just really damn old and death happens. Still manages to accomplish a lot when he was in his prime (and past it a lot of times).
A few other quick questions:
Why does Francis gets one shotted a lot?
Well it is grimdark fantasy so despite potentially being powerful, if someone blows a hole through your chest with a flintlock, you’re dead. And that’s exactly what happens to Casimir in one path.
Casimir, who was kicking Francis AND Semra’s ass at the same time gets killed by Jacob of all people. A simple old bean counter with a gun. (Yes, Francis finishes Casimir off with a sword, but Casimir was already dying of the bullet wound at that point.)
Sometimes the peasant gets a lucky crit with a pitchfork, it happens. Just ask Geralt of Rivia.
Why can’t Francis beat Semra?
Well if he becomes the harbinger he does actually beat her. There’s actually a death ending where he kills her at the same time and he hasn’t even visited Mortos at that point. Which is another great example of despite Semra being powerful, she basically got wasted by a glorified “grunt” compared to her.
Usually Semra stays a certain distance from Francis whenever she believes him to be a danger. So he doesn’t usually have the chance to really try.
Typically whenever they do fight, either Semra greatly outclasses him at the time or he’s a bit more of a match up with her and she takes enough precautions to avoid getting killed. In fact despite trying to stop him from getting the book from Nicodemus and taking it back with him, she doesn’t really do what it takes to stop him at all cost. Semra’s ultimately selfish enough to save her own life at the risk of letting the world potentially burn and Francis is too obsessed with the book at that point to go chasing after Semra when he’s got what he believes to be immortality in his grasp and he can always go kill her later.
So arguably it isn’t why can’t Francis beat Semra, it’s more like why can’t Semra beat Francis since she’s several hundred years older than him with a whole lot more fighting experience and magical power. And the answer to that one is she’s a got a weird Joker/Batman crush on him and not giving it her all like she really should be.
I think that’s it.
Anyway always like elaborating on certain aspects of my stories when asked, so there you go.
