Oh, sure, if you go over to the character deaths thread check out my post where I talk about Dan Abnett for the one from His Last Command.
The point is that generally it’s a Bolivian Army Ending for a reason. Even when it’s not the end of the work, usually you get a post-battle record of their heroism and if it’s a modern setting about the posthumanous metals of honor they earned, and if it’s Warhammer 40k then the Bell Of Lost Souls tolls to commemorate them.
Heck, Battlefleet Gothic Armada was building up to one at the end (it is intended you know this is coming; it’s the Gothic War story and players are expected to know how it ends while they probably don’t know how it starts) when Abaddon has three Blackstone Fortresses and they’re charging up to obliterate a heavily populated solar system, and in the course of the battle you defeat most of his fleet but can’t stop them from commencing the firing sequence to combine their energy into a single beam, and so your character, supreme commander of Battlefleet Gothic, gives the order to retreat, and that’s when one of your battleship captains has his day.
He tells you to cancel that order and he orders his ship to steer directly into the path of the beam at full power, and then he gives a speech to his crew. As his shield start to flare, he concludes it:
“For the Emperor Of Mankind! AND FOR THE BATTLEFLEET GOTHIC!”
And this works; it prevents the Blackstone Fortresses from firing and due to some arcane Archeotech principle not even your Tech-Priests understand this backlashes into the Blackstone Fortresses and shuts them down permanently.
And then the ending cutscene goes over to Holy Terra where they’re adding the names of all those who died in the Gothic War to the list of honored war dead, and that captain’s name is right at the top.
This gets into deeper literary theory, but there’s a distinction between being the viewpoint character and being the main character. Sam is, for the period after Shelob poisons Frodo until Sam gives Frodo the Ring, both.
Much of that is in the narration. It is all in how you explain things. Like how Worm has Glastig Ulaine, who knows a lot and regularly explains things and yet this does not generally result in people she’s talking to becoming more enlightened:
In Interlude 16.z but it's not very informative
When Glaistig Uaine spoke, her voice was eerie, a broken ensemble of a dozen people speaking in sync. “ Beware, Marquis. You will pay a thousandfold times for your arrogance when the armies of the faerie rouse and gather for the last war. “
“Rest assured, Glaistig Uaine, you’re scary enough on your own,” Marquis replied, smiling, “I don’t need a whole army of your kind chasing me down.”
“ There will be no chasing, for they are already in position to strike you down the moment they wake, three hundred years hence. You’re nothing more than the dream of the faerie. I can see it, so vivacious, so creative in its movements, even in slumber. I think it might have been an artist. I want it for my collection. “
He was glad Amelia didn’t challenge the ‘three hundred years’ thing and the notion that they would still be alive then. The ‘faerie’ didn’t react kindly to such.
“You’ve said as much before, noble Faerie,” he said, “Rest assured, you can have me when I’m dead. In the meantime, I will keep your warning well in mind.”
“ Your daughter, too. Your faerie is kin to the one that sleeps inside the girl. I have no doubt this Amelia is a healer, but that’s only a facet of her true strength. I have decided I will not bargain with you, Marquis. “
The important context you need to know is that this is a superhero setting and it’s a meeting of the six cell block leaders in basically Arkham if literally no one ever escaped and Glastig Ulaine is one of the six. Also that I have spoiler-tagged information that identifies a character known from elsewhere and I haven’t tagged anything else because no, what she is saying is not any clearer in context.
I could read Glastig Ulaine narrate sitting around watching other people do things basically forever.
