Bessmert vs Vertin: Different ways of recording eras
So, after finishing the 1.9 event and pretty much confirming that the "Friend from afar" that writes articles for UTTU is Bessmert, I started reflecting on what she does, compared to Vertin, because at the end of the day they're quite similar characters, but with some key differences.
First of, they're both recording eras, but for their own reasons and in their own way. Vertin was given this task by the foundation, presumably so they'd have more information of how the storms work and how they affect historical events (plus, the way Manus interferes), while Bessmert seems to be driven by her own desire to share what she experiences in the form of articles and/or books, which leads me to the second difference; the medium.
Vertin takes pictures of everything she deems worthwhile, as we learn in the prologue, and also presumably makes some paintings, both of which are purely visual mediums. Meanwhile Bessmert, for obvious reasons, could never use those, and instead turns to writing.
But the major difference, imo, is what they choose to record. Bessmert writes about historical events (the theft of the world-famous rimmet cup, and how an unknown little town in the middle of nowhere saved itself and became prosperous) or major geological arcane discoveries (Pei city and it's Divination, and presumably Aperion and it's magical cave). Meanwhile Vertin records what she herself, personally, finds interesting; the single mother who wrote a play about the transantartica expedition, and a girl who had a collection of a futbol player photos are a few examples. Of course, some of the pictures she took happen to be of historical events, like the Apollo 11 launch, but they're not all she records.
What's even more interesting, however, is how Bessmert detaches herself from the narrative; she's never a protagonist in the stories she writes, and she doesn't try to influence their course or make connections with the people she meets; she's simply an observer. In Shuori she was forced to participate in the the story due to circumstances beyond her control, but even then what she wrote about the event seemed to be more like... collections of geological and cultural observations, rather than anecdotes of the people she met, or what she felt during the events.
Vertin, on the other hand, tends to be an active protagonist in any story she is in. See Green Lake and Uluru, for example; she interacted with the characters, helped them, used whatever resources she had to influence the story for the better, etc. Not only that; she formed personal connections and even invited them to the foundation and her suitcase, because this is the most valuable thing that Vertin deems worth preserving of each era; the people she meets and the bonds she made.
Vertin goes against the wishes of the foundation, to record what she sees without sparing any feelings for the people she met, while Bessmert... well, she really would be the ideal Timekeeper, wouldn't she?
