Genshin Impact: Memories of Water, Return of the Gods

Zhongli CP. A mountain of headcanons. After the war in Khaenri'ah, the soul of the former Hydro Archon, Egeria, drifted to the modern world, where she grew up. Later, a game called Genshin Impact came out in this world, and Egeria became one of its veteran players. However, she had no memories of Teyvat. It was only after completing Fontaine's main story that she remembered, found a portal, and returned to Teyvat.
