the astral express family as a unit is SO important to me.
starting with the trailblazer. confused, used, and hardly remembers anything about who they were before. the stellaron in their body is essentially a ticking time bomb. the personal fear that comes with that is already immense, and that's not even taking into account other people's perceptions. but they were accepted, immediately, stellaron and all. they aren't feared, they're loved. instead of others being protected from them, they're protected from others.
dan heng. scared, lost, and without a home to return to. his past tainted every step he took on the xianzhou, and despite the events of the main story, he's still working through how other people see him, as well as how he sees himself. he's never truly been SEEN before, not as dan heng over dan feng. but he's finally been given a place of acceptance. people who love him as he is, with no attachment to his past self. he's found not only a home that he can always go back to, but a home he WANTS to go back to.
march 7th. the girl who doesn't even remember her own name. we as people are shaped by our memories and out pasts. how can someone so young cope with the great unknown constantly looming over her head? companionship. compassion. the promise that no matter what that unknown brings, she is no longer alone. a hand to hold in the darkness, to guide her through the worst that the universe can bring.
welt yang. loss and grief have shaped the person he is today. the threat of the honkai means the constant fear and application of losing the people most important to you. to have a family in the world of the honkai is just about the most dangerous thing you can do, and he knows this firsthand. his memory is not tampered with, but rather incredibly clear. he was a child when his life was overridden by duty, and that duty is something he refuses to let go of, even now. but these people don't see his duty when they look at him. they don't see the herrscher of reason. they see mr. yang, the ever-reliable, slightly ancient, kind member of the crew.
himeko. everyone on the express will come and go, and the life of a nameless is an inherently lonely one. attachments cannot be too severe, lest severing them ends up destroying her. but here she is, with all her knowledge, loving these people anyway.
memory and acceptance are both key themes with the entire express crew. not just past memory, but the creation of new memories. better memories. the express is a place where who you are is inconsequential, and all that matters is that you're safe now. you're loved now. and you will be loved, no matter what happens. no matter what you do, say, or choose.
and something so constant is the glue that holds this group together. not only that, but something they all desperately need.
the trailblazer, young, confused, and scared, needs something to remind them that they aren't alone. something to latch onto, something to cling to that grounds them through the turmoil of hosting a stellaron. dan heng, the greatest criminal of the vidyadhara, needs something to remind him that there is hope. that his life will not always be weighed down by the mistakes of his predecessor, and that there are people out there who love HIM, just as he is, with no fine print or strings attached. march 7th, with nothing behind her, needs something ahead of her. something real, something concrete, something or someone that she can tangibly see, feel, and hold. the uncertainty and unknown hang over her head like a cloud, but that darkness feels much less scary when someone can hold her hand and tell her she's not alone anymore. welt yang, who's lived so long, been through so much, and lost so many, needs a new beginning. not that he's leaving behind the ties he has left, but forging new ones, with absolutely no strings attached to the identity of the herrscher of reason. think about why he never mentions his past in full; obviously for a multitude of reasons, one of which the subconscious desire for a life untainted by the honkai. and himeko, who left everything behind for her dreams, needs people different than her. something new. like-minded people follow the same principles; fulfill their life's purpose, and exit the express. however, in the midst of all that, she's gained more than colleagues, more than nameless, more than fleeting images of friends long gone. she's gained the unconditional love of a family.
and that's not even getting into the dynamic between just welt and himeko. the fact that himeko always feels alone, and then there's welt, who travelled the very cosmos just to protect the life of a former student he feels like he failed. the fact that she likely has no idea of this fact, and assumes he'll leave the express and return to his "real" family someday, when in reality, the only reason he stepped foot on the express in the first place was FOR her. BECAUSE of her. to protect HER.
i'm gonna be honest, even though void archives hasn't made an official appearance yet, and their motivations are obviously skewed due to the fact that they're not technically human, i would fit them into this too. they were never intended to live their own life. their origins and their programming prevents that. destroy the honkai, above all else, no matter the cost. after millennia of being trapped by otto, their own identity, what little of it existed, slipped through their fingers. why do you think they hate being compared to him so much, despite adopting so many of his patterns and mannerisms? what they need is a life of their own. which connects so deeply with what welt needs, too.
and i'm just spitballing here, but i have a theory that part of the reason they left the express in the first place was because they were afraid of the comeraderie they found there interfering with the reason for their existence.
addendum; if the stellaron is in fact a manifestation of the honkai, i NEED to see how that changes the trailblazer's relationship with everyone. especially given the fact that void archives was created to eradicate every form of the honkai, no matter the cost....
anyway. all this to say. i love the express family so much.
