In every day life, she appears as a calm, polite and reliable person, but with the air of someone who respects a very strict type of etiquette, never really having strong emotional fluctuations, she is always ready to offer word of advice to whomever might need to hear it. Although one can distinguish a very tiny hint of detachment in the way she does things.

In contrast to her usually serene demeanor, she can become stone cold and merciless at times, rarely losing her composure or showing any kind of emotion that may drive her actions, dropping any pretense she may have held before.

Permanently straight and elegant posture, sometimes complimented by gentle and graceful hand gestures, but aside from it she rarely exhibits movement that can betray her emotions, preferring to come across as unphased and collected.

In private, her mannerisms lean towards a more mundane variant, showing some slightly more natural emotional gestures, although these somehow feel like a thin layer used to mask the fact that the cold persona is actually the real thing

Keeping her new found home and the control over it

She has a rather unusual understanding of this world's meaning of life, as its very different than her original world's.

She mostly views her actions and the things around her as maintaining a well oiled machine, so any deviation from the norm is seen as a mistake that needs remediation promptly.

Near desperation to have things her way, which can lead her to become very destructive if impeded.

Losing all that she has worked for to achieve

As she's an established fangirl for weapons of all sorts, she learned to not just wield them, but also make them

Taking long walks at night through the garden.
Collecting weaponry - they're one of the few things that genuinely bring her happiness (hence why a lot of her tools are weapon shaped)

None stated so far - she seems to like ferrets

She gained a certain fondness of grilled meat, with various seasonings.

Her custom armory - where she stored her Star powered set

Double khopesh looking blades or just scimitars in general

She does not align herself with any form of belief or deity, as she herself poses as one.
The only form of religious tie would be with her former unnamed creator

While maintaining herself separate from the nation's leader, she has reached the conclusion that maintaining a stable nation provides the most resources and the best results, therefore she has established an as fair as system as possible, strictly cracking down on any and all forms of corruption.

Royal advisor

the notion of a favorite color is a little ridiculous to her, but if she had to pick, it would be purple

She comes with a great deal of wisdom from her previous nation that she has learned to apply to the current world she resides in

Originally one of the many divine creations of an unknown god, she now remains the last of what was once the thriving world of the stars. She had left her homeworld to explore beyond its boundaries to quench her curiosity, only to then discover upon her return that her former realm had essentially blipped out of existence with absolutely zero explanation, leaving her both alone and searching for answers.

After a long time spent wandering the infinite void, she eventually crashed on to an obscure realm brimming with life. It was here that she discovered the resting place of the unknown god's remnants, now once again revitalized by the realm's native essence, leading them to birth several types of new creatures, among which were the Morphidae.
In her exploration of this world, she became acquainted with one of these creatures, beginning a sort of friendship where she shared some of her knowledge with them to test out their potential.

While mildly intrigued by the new creatures, in time she realized the alien origins of the core which powered them allowed her to grasp the new world's essence, something previously impossible through direct contact, due to her not belonging to the place.
This started her on her path to integrating herself within this new world, by robbing morphidae of their cores and then experimenting on them to better her understanding of the new type of essence.
Soon enough she discovered how to create tools that allowed her to gain control of all the present powers, which eventually led her to once again meet the young morphidae whom she had once helped nurture, now desiring his powerful core more than anything.

Through deception at the end of a hard fought fight, she managed to rip out his core, and with it, created a took that completed her set, meant to aid her gain full authority over the powers that be.
In the meantime, she slowly crawled her way into politics, learning the art of leading and slowly rising in ranks throughout the nations she infiltrated into. In time she took a liking to her current style of leadership, keeping it separate from the actual leader, as she believed it more fair if the masses were ruled by one of their own who knew better what the needs of the people were; meanwhile her position allowed her to remain there regardless of the changing times.

In time, she became revered as a god by the people she presided over, a title she is striving to live up to until current day.

Sacrificial fire - when using their true form, they can unleash a special type of flames that consume anything they touch. These flames cannot be put out by normal means

Shapeshifting
Elemental manipulation
