The stars are for you [Honkai:Star rail fanfiction]

Extra: the elements

Anemo, a version of Rex Crozzo also known as Cerberus, is a young man with eyes that looked like two expertly carved diamonds. His dark hair danced with the wind as he floated in place in his domain, a place that he had managed to build by himself, hiring numerous archon versions of himself to live and maintain the place. The archon hall, the name of the palace he had built with only an entity called 'Rex Crozzo,' can enter. 

"Gnoses, powerful artifacts from the world of Teyvat, are what essentially bestows a being the title of an Archon," Anemo whispered as he gazed at the glowing queen chess piece in his hand. "The Gnoses are the embodiments of the Heavenly Principles' control over Teyvat and of the "laws."

Little is known about the full abilities of the Gnoses. So far, they are said to resonate with Celestia directly and grant their respective Archons the "divine ability" to defend their nation.  Nahida's understanding of the Gnoses was limited to knowing that they could be used to summon a mass of elemental power at their owner's disposal. 

The Gnoses, while powerful, are not required to manipulate an element by itself. After all, Geo, now known as Cerberus, had given his Gnosis up for a foolish wish. Despite this, he has retained his abilities to use and harness the power of Geo, despite not being as powerful as he once did. It also serves another purpose as a beacon of sorts, I do not know why but I have a theory that it involves Celestia, the abode of the deities of Teyvat.

A Gnosis can be seen as a power source, similar to a nuclear reactor but without the danger if unkempt. Rather, it would only be dangerous in the hands of someone else. Electro has managed to find a way to use his Gnosis to attain a way to enter the metaphysical realm of the Archon hall, although I suspect that my electro counterpart's other half helped him. 

The gnosis is the counterpart that Teyvat has to Earth's Herrscher cores. Just like Gnoses, Herrscher cores allow their user to control an element. The difference is that while Gnoses (presumably) allows its user to act in accordance with his desire, the bearer of Herrscher cores is, in one way or another, under the influence of the being known as the Honkai. 

By their own, Gnoses pale in comparison to the Herrscher cores. After all, the Herrschers themselves can control concepts and reality as long as it is related to their elements such as the Herrscher of Reason's ability of creation as long as they know how it works. 

However, a battle is not won by pure might alone. 

In fact, in terms of pure combat ability, the archons of Geo, especially if they have undergone what I call the "Bleeding process", will be more than a match against most of the Herrschers without preparation. 

Concepts

In terms of concepts, the elemental Gnoses have their own concepts, imprinted onto them by their former owners. Sadly, the more compatible one person is to their gnosis, the more powerful their compulsion to their concept will be. 

My elemental Gnosis of Anemo has the concept of Freedom imprinted on it. It has influenced my desire to be free, to be unbound. Unbound by notions and bounds that tie my potential. I have broken my chains. 

The elemental Gnosis of Geo has the concept of contracts imprinted into them. The holders of this Gnosis are more often than not, loyal to a fault. Binding themselves in accordance with their 'contracts', one-sided or not. 

The elemental Gnosis of Electro with the concept of Eternity. Its former owner and possible consciousness, Makoto Raiden, still lives and has become engaged to my Electro counterpart. 

Dendro, the element of wisdom. While not the strongest in straight fights, their abilities make them the worst kind of people to fight. Especially since their most terrifying ability to analyze and pick your entire being apart in their samsara.
