Which is where epic fantasy picks it up. Lord of The Rings certainly deals with world-shaking events; win or lose, nothing was going to be the same after the war.
So I noodle with the notion of a story set in a fortress that is holding off evils from beyond, and it starts long after the fortress was founded, and all the legal preogatives set up -- only one character from that era even gets mentioned -- and nothing from the entire story even hints that it will ever end.
Except, of course, by failure. So in another sense it is dealing with world-shaking events. Every serious challenge, if failed, will bring ruin and disaster. It's like a ladder, or a bridge -- if one rung, or one part of the span, is missing or untrustworthy, the whole thing is a failure. (Scribbles down the metaphor for use in the story. The bridge, probably; they do have ladders, but the bridge is more what they would be thinking.)
To be sure, the story does not revolve about these events, but about a character who ends up at the fortress and what happens thereafter. The important ones for the story are those that affect her. Because even extremely high stakes are not a story if they don't produce change, and she's what's changing in this story.
