Scylla wasn't the direct founder of Remuria, but played a crucial role in its establishment. This is revealed in the Sea Origin Broken Lyre ingredient, stating that when the first usurping king arrived at the Genesis Sea, the former ruler of the Hydro Nation gifted him a cup of water. Subsequently, he ascended to godhood, using this cup to refine a dewdrop gem, thus founding a prosperous empire.

The second deity in the history of Teyvat is none other than Egeria. According to current information, Egeria seems to be an ancient goddess. In the Wings of Freedom and Fury, miHoYo refers to the Water Dragon who once ruled the nation as the 'first heart of the Primeval Sea.' The leader of Celestia then created a new heart to replace the Water Dragon after defeating the seven dragon kings.
Egeria is a being 'created by the god of humans, with materials and nature being original elements of this world, containing no elements from outside.' In her role as the new ruler of the nation, she seeks connection and understanding, a journey that brings the goddess to tears multiple times. 'And it is precisely this empathy that led Egeria to commit acts of transgression known to all inhabitants of the nation.'

The birth of Egeria is not just a whim of the First Being but is in line with human desires. 'Humans crave judgment for the sense of guilt, and humans desire order for chaos... Humans always want a god. Therefore, the heart of the Genesis Sea, Egeria, mercifully received a shard from the First Being, with the dignity of an Archon and a sacred, belated mission.' We have reason to speculate that the 'shard' is none other than the Gnosis, a part of the power to govern the nation that the Water Dragon possessed before.
'Remus' Transgressions'
In the previous part of this Genshin Impact storyline, you learned about the great emperor Remus, who founded the ancient nation Remuria with the assistance of the Water Dragon Scylla. As this nation flourished and expanded, surely Scylla accepted subjugation under Remus as a means to secure peace. The great emperor cared for his people, constantly adjusting the 'notes of the symphony across the entire land' to create an eternal kingdom.
But at some point in his reign, Remus underwent a transformation. The reason for this change is likely the prophecy of Remuria's doom. The Wings of Freedom and Fury succinctly narrate the career of this imperial deity: 'The great Remus arrived at Fontaine, in his vision a grand and eternal city: Remuria. He educated its inhabitants, and finally touched a corner of his dream. Following that, a statement not malicious but terribly frightening from the prophet: The final golden melody will conclude, and so will Remuria perish.'

It is often said: 'If a hero returns home without perishing, they will surely become a tyrant.' While Remus slept in an attempt to seek an escape from fate, the four Harmosts to whom he delegated ruling power over the kingdom became cruel tyrants, executed through notes and in the name of righteousness that Remus so proudly embraced. This cruelty sparked a fierce wave of resistance, and the great Remus earned new titles: Remus the fool, Remus the farsighted, Remus the lonely. But whatever the title, Remus had lost the hearts of the people.
This is recorded in the sacred relic, the Golden Feather of the Phoenix, stating, 'The esteemed maestro adjusted the melody, and the legion of gleaming armored steel arrived, taking everything from everyone. Even the resilient, unconquered ones, who had not lost a drop of water, united again, pledging to resist to the end.' Even the dragon king Scylla, who once assisted Remus in establishing his mighty kingdom, stood up in resistance, labeled by human history as the 'Lone Dragon.'
The oppressive forces of Remuria encountered the resistance led by Scylla. The description of the Silent Hymn Bow states that the 'savage' army, consisting of humans and Vishaps led by Scylla, attacked the gates of Remuria. The golden age abruptly stagnated, plunging Remuria into endless war and rebellion. Ironically, this was also the time when Remus awoke from his long dream.
