Hello trailblazers!
After an admittedly very VERY long pause due to me getting sucked into a certain videogame that begins with "T" and ends with "he Legend of Zelda: Tears of the Kingdom", I'm finally back to writing now that I have some extra free time and can do both! I suppose it works out as now we're pretty close to Silver Wolf releasing meaning that her stuff will come right on time!
But I digress, today we're here to talk about Bronya once again!

But before, we have our disclaimer!
The Honkai: Star Rail characters and Honkai Impact 3rd characters who have the same name and similar appearances, except for Welt Yang, are NOT the same person, but instead you may think of them as something akin of parallel versions of each other! I go into detail about this and how the Honkai universe works here!
Also, big spoilers for Honkai Impact 3rd ahead, be warned!
Now then, let's continue Bronya's story, which we cut off after Bronya and friends met up with Rozaliya and Liliya and then Bronya decided to go into the Sea of Quanta, after the Gem of Desire and to possibly find the long lost Seele! You can check out part 1 here!

The Sea of Quanta

After entering the Sea, Bronya was faced with multiple trials. As she hopped between Bubble Worlds, fragmented parallel worlds that floated in the Sea until they became nothing, she met with the one she wanted to see the most, Seele. Not a parallel Seele, but the one she had always known. She kept following her through many worlds, but these worlds would come to an end before she was able to do anything. As she dives deeper into the Sea, she meets with Joachim, a shadow of the current form of Welt Yang, who acted as a sort of "guardian" for the Sea after he had become lost there during an expedition him and Einstein had taken to explore the Sea.
Bronya and Joachim
Joachim reveals that Bronya currently finds herself in a labyrinth, which is Welt Yang's current form, with the different worlds being manifestations born of his memories. Bronya continues to travel onward, guided by a book that connected her and Seele. Through many worlds and corrupted memories, Bronya continued to move forward, no matter what. Seeing that she completed this trial, Joachim entrusted Bronya with Welt Yang's Herrscher core, that of the Herrscher of Reason. After doing battle with the evil being within Seele, who had made a deal with someone who used the form of a serpent to get Seele out of the Sea in exchange for Bronya's life, Bronya completes her metamorphosis.

After defeating the monster known as Tlaloc, Bronya continues to search for Seele, and she finds her after she exits a bubble world created by the Serpent, who is revealed to be Kevin, a man from the Previous Era. They are locked into battle, and Kevin steals the core from Bronya, whose movements are now slowed after she's done so much travelling within the Sea. However, Welt Yang's will allows him to reform from the core, stopping Kevin from taking it.

Kevin takes the Gem of Desire and leaves the Sea. Welt chases after him, and Seele now brings a tired Bronya without powers with her to leave the Sea. After many tribulations (and a cool cutscene), they are able to leave. Kevin has escaped with the Gem. Welt decides to give Bronya the core to keep, as he believes she has more potential while using it.
The next time Bronya is seen is when she and Kiana go to climb Mount Taixuan, where they find many of the memories of their class principal and mysterious girl Fu Hua. This arc, though very complex and important, does not give much to Bronya as a character, and I'll thus leave it with just this small mention (though I'll add something here if I've forgotten it!)

Bronya's Training and Other Arcs

Later, we find that Welt Yang is training Bronya in how to use the Herrscher core. As she trains, she also has recurring dreams, including finding herself in a wasteland and seeing a figure of a man, who she attempts to approach but wakes up before she is able to. This is Bronya experiencing the site of the First Honkai Eruption which originally gave birth to the Herrscher of Reason, Welt Joyce, the very man Bronya sees during the dream.
Welt Joyce appears in Bronya's dream
Welt Yang explains that the Herrscher of Reason can only contruct things that they know the composition of. For example, Bronya is able to replicate a gun she is familiar with perfectly, able to fire and all, but is unable to do so with a gun she is unfamiliar with, having to dismantle it to learn each component. He shares that he also saw the dream Bronya did, and it was more of a fragment of memories and the wills within the core, those of the 300,000 people that died during the First Honkai Eruption.
From here, the Herrscher of Domination incident begins, and Bronya and Seele, along with many of their friends, battle against it and its unique powers. In the climax of the battle against this Herrscher, Bronya, who had been knocked almost unconscious, gives a fragment of the Herrscher of Reason powers temporarily to Kiana, allowing her to gain new powers and defeat the enemy.
After this incident, Otto Apocalypse (Schicksal's ruler) begins his master plan to "revive" his fallen love, Kallen Kaslana. Though the entirety of the main cast and their friends are involved in this plan, Bronya is once again not given a great deal of importance or new developments. She and Seele work together most of the time, with Bronya showing her concern for Seele's safety. Though Bronya now controls the Reason powers properly, there is still much she is unable to do, and she has a limit to the things she can create, as some things require more energy than she can output.
When she battles Rita Rossweisse, she remembers the path she has taken as the Herrscher of Reason, and doubts her ability to be the successor. But she understands that, even if she cannot carry the weight of the world, as the previous Herrschers of Reason had done, she can provide help and do it along with her friends. She is then able to create a copy of the Star of Eden, the Divine Key used by both Welts.
Bronya utilizes the Star of Eden
In order to use the Star of Eden's power, Bronya continues to create them as they are destroyed, as she cannot create a stable one with her current powers.
After Otto creates a barrier around his location using the powers of the Herrscher of Binding, the cast attempts to shoot it down using the Selene, a high power cannon that neutralizes Honkai energy. However, the barrier regenerates too fast for the blast to be able to work due to the charging time of the weapon. In order to break the barrier, Bronya decides she will use the Reason powers to create an array of Selenes and blast it open before it can regenerate. To do this, she must reach into the core and communicate with the 300,000 souls that rest within it. She is able to convince them to help her, and is even able to approach Welt Joyce, and thus she is able to concentrate some of their power.

By synchronizing the thoughts of the 300,000 to a certain degree, the Herrscher of Reason's power is augmented by a fantastic amount, allowing Bronya to fulfill the mission she set out to do and create multiple copies of the Selene to break down the barrier, before fainting and coming close to death due to the amount of power taking a burden on her body.

Project Stigma and the Moon

Later, Kevin and his organization World Serpent initiate the Project he had been in charge of for 50,000 years, since the Previous Era, a last resort to defeat the Honkai. Project Stigma consisted of creating a shared consciousness that would not be affected by the Honkai and could then pass on its powers to the next era of humans through becoming Stigmata engraved into them. Of course, this, despite being a plan that would not fail against the Honkai, was nothing short of immoral, as it would technically mean killing every human on the planet.
Bronya along with Mei and Kiana, all of whom are Herrschers, are sent into the Sea of Quanta by Kevin to keep them from interfering with the plan. After the girls reunite, they find a bubble world where they meet Dr. MEI and Prometheus, a scientist and an AI from the Previous Era. These two want to help them stop Kevin's Project Stigma, and eventually help them leave the Sea.
Here they meet Hare, an ally of Kevin who was in charge of sending humans into a "dream world", which connected to form the shared consciousness. She is not human, but instead a crystallization of a Stigma, basically the humanoid form of the Stigma's perfected form. Specifically, she is that of the Schariac Stigma, the purest representation of the Schariac bloodline, of which Kiana's mother, Cecilia, was a part of. We also discover that Hare, also known as Misteln, had actually met Bronya's mother. It seems that Bronya's mother had known what would happen to her upon Bronya's birth, and Hare had used her Stigma powers to keep her alive, but she had refused as that would mean the baby wouldn't survive. With a heavy heart, Hare took away the power she had infused her with and left before the mercenaries of the Silver Wolves arrived. She later returned to find nothing more than a grave with Alexandra's name. From here on, she kept an eye on Bronya since her early life.

Hare locks away Bronya's Reason powers by splitting the 300,000 wills from the core through her powers. Bronya takes the core, now with only 1/300,000th of its power, and battles Misteln, who has taken all the other souls into Project Stigma. Through defeating the soldiers Hare created from fragments of souls, she regained her power over time, and eventually, through the realization that the 300,000 are not the solution to every problem and that they are not the entirety of the core's power, she is able to surpass what she had done before, harnessing the complete power of the Herrscher of Reason, becoming the Herrscher of Truth.

She defeats Hare, and from here, her, Mei and Kiana are able to gain new power and eventually defeat Kevin, putting a stop to Project Stigma and ending part 1 of Honkai Impact's story.

8 Years Later

After defeating Kevin, Kiana, through her newfound powers, was able to take most of the Honkai Energy on Earth and keep it concentrated on the Moon, where she would have to stay with it for around 10 years before she was able to make it into something that could be used by all of humanity, effectively ending the Honkai crisis. Meanwhile, Mei, Bronya, and the rest of humanity went back to their normal lives. Both Mei and Bronya would work with Schicksal, now ruled over by Theresa Apocalypse, to keep the world at peace and make sure nothing would once again threaten the world. Though there is not too much to speak of here, we do get to see Bronya 8 years after the end of part 1, through the side mode known as A Post-Honkai Odyssey.
Adult Bronya
Though not directly addressed in APHO, Kiana sealing most of the Honkai Energy means that Herrscher powers are almost completely lost, meaning Bronya no longer has access to nearly as much power as she did during the end of part 1. She is now acting as a squad leader for one of Schicksal's squads, and she helps he main character of APHO along with his friends fight against the Sky People, an alien race that invaded Earth to take its Honkai Energy and replace humans as the dominant species, with the aid of a "man" known as Void Archives.

The End

Bronya's story is one that goes through many phases. She begins as a stoic, almost robotic girl, both due to her being raised as an assassin and due to the loss of her brain functions pretty early on. Even here, she demonstrates her love for those she cares about, especially Seele. As she inherits the Herrscher of Reason's core, her destiny becomes inevitably intertwined with that of Welt Joyce and Welt Yang, having her become part of the history of their lineage. She becomes a pupil to Welt Yang, almost like his own family, and her journey revolves around finding her own path and realizing that she, unlike Yang, does not need to inherit the "name of the World" to be worthy of the name of the Herrscher of Reason. In the end, she surpasses all attempts before and perfects the core, being a fundamental part of the battle to save the world and all of humanity, as well as the efforts to rebuild after the Honkai crisis is over.

Bronya Zaychik and Bronya Rand

Finally, we can think a bit about the similarities between Star Rail and Honkai's Bronyas!
Both have a strong sense of duty and justice in their own way. Bronya Zaychik from HI3 always thinks of the lineage of the Herrscher of Reason and the duty she shares with the Welts that came before her, while Bronya Rand from HSR feels her duty as the leader of the Silvermane Guards (and later as the Guardian of Belobog) more than anything. Besides this, we can find that both were adopted by Cocolia and raised in an orphanage, where they both met the respective Seele of their world and created a strong bond with her. Besides this, Bronya Rand's relationship with ice, even in her art, can be connected to the fact that Bronya Zaychik, though only related with ice through her growing up in Siberia, has all her relevant battlesuits as Ice element (Herrscher of Reason, Herrscher of Truth and Silverwing, her adult form).

Closing Thoughts

Thank you for reading all this! It took a while to get here, definitely longer than I had originally expected lol, but hopefully it's a good read! As always, for any Honkai veterans or just anyone that knows, please let me know whatever I may have gotten wrong!
I want to point out that perhaps these 2 parts may not seem as well put together as Welt Yang's analysis. This is because Bronya, though a very important character within Honkai Impact, is often shoved to the side and is considered the least relevant of the original main trio. Often times she will disappear from the main focus of the story for an extended period of time, meaning her story is more fragmented, and I had to show her most relevant moments, meaning that it feels more like talking about different sections of her life as if they were fully separated. It's a bit unfortunate, but hopefully it's to your liking anyway!
Regarding Silver Wolf, I've decided to tackle her in part 3! There I will discuss Silver Wolf's origins in the HI3 world, along with discussing the very varied versions of Bronya that exist across all the HoYoverse games, because there are many and they can be quite confusing! This part 3 will (hopefully) be released on the date of Silver Wolf's release in Star Rail, so look forward to it!
For now, thank you again for reading and give me any suggestions or opinions in the comments!

I have been diligently monitoring my account each day, and now that I've been released from jail, I'm finally free. I'm excited to start the process of finding a home, even though I know I might encounter additional charges, humorously referred to as "Biden fees". Overall, I am content and immensely grateful for my newfound freedom
