First off, your tone is excellent. You maintain it throughout the story, and that is paramount to keeping a reader reading, in my opinion. Secondly, that tone is exceedingly dour high fantasy, something I love desperately, so this piece is right up my alley.
It's clear a lot of effort went into this, and it shows- the passive worldbuilding is fantastic, the magic system leaves just enough for the imagination, and our narrator is characterized enough for us to believe they have such writing skill. The prose is well spaced and vivid enough fir the imagery of the world to plant itself firmly in my head, but overall I find some of it lacking. Why not describe the inside of the Southerners mansion, giving us more worldbuilding and lore along with interesting descriptions of art? Not to mention the lack of interaction with Gomman, who would most likely have interesting opinions on both her husband and the land they live in.
Overall, this is good. The mode of writing may lead one to believe it's written roughly, but I can see definite skill in everything. You have a good grasp of plotting and character work, and I'm interested in seeing more of what you write. What I want from this piece is more! More Journaling, more of this world, more of these characters: flex those writing muscles abd see what you can do. This is still postable, but I think it would benefit from some expansion.

Rather than have an ellipsis present between sections, I would suggest using a page strikethrough. I'll include one below. It's 6 - strung together.
