Isnt HP supposed to be Reason ? In Aubade of Morningstar and Moon, it mentions that HP choose Order to rule Teyvat and Order is capitalized here.

I think the key word here is "choose", as the HP used its REASONing to decide "I'll just restructure a space somewhere to accomodate my own idea of order to prevent destruction, like what happened to previous stars".

Order in this context could mean something like "law" or maybe "principles" that would govern Teyvat. You need "reason" to craft those.

Order over Chaos.


Although the act of creation is often thought of imposing order onto a pre-existing chaos soup.


And civilization is the act of imposing order via the creation of rules and laws to bring humanity out of the chaos of the state of nature.


Dragons are part of the original land. They are part of the chaos of nature. The dragons are the threat of the encroachment of the chaos of nature. Storms, disease, drought, volcanos, earthquakes, floods, lightning, etc. Slaying or at least conquering and pushing dragons back is mankind overcoming the threats from nature. Burning down a forest, building a dam, draining a swamp.


But what happens when the weapons given to mankind for fighting back against the dragons are turned on the gods who gave them?
