She is willing to achieve her goal:overthrowing the heavenly principles and/or celestia with whatever methods available. Including employing morally questionable people like Dottore.

Venti mentions how she has never been the same since the cataclysm 500 years ago, it is likely this is what made the Tsaritsa make up her mind about rebelling against Celestia.

Appearance speculation(Honkai references)

Reference character: Bronya Zaychik/ Ana Schariac

Reasons why Bronya Zaychik could be a base:

Bronya Zaychik’s nationality is Russian, and Scheznaya’s real life reference is Russia

She is known as the silver wolf and was a child soldier from a young age.

She also had to harden her personality after going through a traumatic event.

One of her battlesuits is ice-element oriented(Herrscher of Reason).

Although I do not belive she is the main blueprint for the Cryo Archon of Genshin. Her real strength as a Herrscher(god) is not related to Ice. It is creation, meaning making things once you understand/memorize its structure.

Plus, honkai already got an Ice Goddess with tragic backstory.

Why I think Ana Schariac is the main reference to the Tsarista

Just take a look at her title. Herrscher of Ice

And her design. I do think mihoyo would surely not let a beautiful work of art like this to go to waste. All this work and Ana would just be an NPC with so little screentime? (Rememebr Wendy->Venti, please make this a treand oml)

Does her color scheme reminds you of the Fatui-centric pale flame artifact set?

A major argument Ana has is: Her tragic backstory and the potential parallels. The theme "love" is very much present.

You can argue that Bronya became the herrscher of reason to help her friend is also tied to love in some way...

However Ana's story has major similarties to the Catalysm happened 500 years ago and why the Tsarista become a different person.

My personally wish is this: Since Ana did not get to live long enough after become a herrscher and we know little about her personality, the Tsarista would have Bronya's personality and way of doing things.

How the Tsarista met her first Harbinger, Pierro

This is the Story on the Mocking Mask of the pale flame set, implying he is from the Fallen Kingdom of Knaeri'ah. He was taken in by the Tsarista, it would seem.

In Honkai, Ana also saved someone important to her from a disaster. His name is Chen Tian-Wu, code name Owl.

It is implied that they love each other. In fact, Owl stayed by her side until the very end of their lives.

In Honkai, Ana ran away from Owl's dying sister so she would not see her die. Note that it is not because Ana did not want to, but the littl girl is beyond any help at that moment.

This could very well be a parallel to how the Tsarista can only turn away from the descruction of Knaeri'ah since she cannot do anything, cannot invervine the decisions of the heavenly principles/Celestia

Owl later found out about this, and he was not sure whether or not to hate her or be thankful to her. (The Jester Pierro could have the same mindset since formentioned parallels)

Ana felt immense guilt regarding the fact that she ran away and it eventually led to her hersscher transformation.(Losing your mind etc)
