That last post is getting more popular than I expected, I would've tried to articulate my thoughts better if I thought more than like 2 people were gonna look at it lol. So here is a somewhat more formulated thought on it!
I think it's fascinating how grief, love, and change are all three woven so profoundly together throughout the entirety of FL that it's impossible to tell where the seams are between them in some spots. All three are variations of the same sort of sentiments, three sides to one coin, for lack of a better analogy. One blends into another, they inhabit the same spaces in the story, and even when they don't overlap, they still resonate with and parallel eachother
But I think it's especially fascinating how grief runs through it, given that in the Neath, permanent death is a relative rarity (to the point that you get cards specifically calling upon you to sit vigil with corpses to ensure that the death is truly permanent, that there really isn't another chance.) But people don't just grieve death, and there is so much loss that permeates the story and the setting in a way that you encounter it in different storylines over a lot of different things (a loss of freedom, of a love, of an opportunity, of a mind, etc), and it's one of those things that I think about a lot for the setting
We know that Love is one of the strongest themes that pops up in FL ("in all things, look to love") but I just think those three things are linked together in a way that makes it impossible to truly untangle them, and that they warp and melt into and around eachother. Grief is love with nowhere to put it, as someone once said rather eloquently, but to love is to change, to change is to grieve, to grieve is to love
