Hi author...
It seems you provide a variety of knowledge to the MC from clueless to lore nut, so my ask is when MC could use this knowledge to their benefit? While I understand this probably could make drastic change to the original story, surely there has to be somewhere the narrator no longer intervene? I mean MC is alive and this is their new reality, to not interact and able to influence outcome seems weird.
OKAY. So. Flavoring this with a warning that I spent most of today trying (and failing) to save one of my new corydoras (this is why you quarantine your new fish folks) and treating my QT tank to try and keep the others from getting sick, when my day off was supposed to have been spent writing so my apologies if I sound a little more abrupt than my awkward ass already usually is.
I have reasons that the Narrator (capitalized for character, versus me as the narrator) does what they do and how they CAN, and a big one with making this choice a thing is because I needed to draw the reader's attention to the Narrator. So. Yeah. It's kinda supposed to seem weird? That's the feeling that is supposed to happen there - it was deliberately meant to put a reader's hackles up about the Narrator and make y'all go "yeah, this is SUS".
The MC can use that knowledge to their advantage, but not YET. This is early days in the game, even in the rewrite the attempt to warn or change anything remains a non-choice: you cannot save the MC's and Auberon's parents. There is nothing you can do to stop the Empire. Nothing you can do as a child will ever change Ausones' fate.
Remember, folks, there is always an agenda behind every narration and every narrator has at least one that they may or may not be sharing.
