This headcanon concept has been living in my head rent-free, so I’ll just share my thought ms on it. All relationships mentioned are platonic, non-romantic bonds
So, I was thinking about writing a fanfic of the Natlan archon quest, but from my main team’s (Cyno-Furina-Nahida-Shinobu) POV. Basically Furina hears that the Pyro Archons were ordinary humans with a mortal’s lifespan, and she keeps thinking, what would’ve been if she was the Pyro Archon and not the Hydro archon? She shares these thoughts with Cyno (who she’s very close with) and he finds it weird at first, as she cannot back out from the Pilgrimage once it begins but tells her that if she makes up her mind, he will support her though it.
Side-note: Furina doesn’t have much combat experience, but she gets determined and decides to train her physique, both from Cyno and from Mualani (since she is also a Hydro wielder).
Also during the AQ, the Salon Members merge into a single entity called the Leviathan, strongly resembling Neuvillette’s draconic form (see his constellation). As Furina develops her combat skills and starts to utilize her vision more and more, so does the Leviathan becomes more powerful. Unlike the Salon Members, it becomes more like a tangible familiar (similar to Man Tsai or Ushi) rather than an illusion, slowly gaining sentience. After the Night Wars, when Furina becomes a Pyro Archon, Leviathan gets imbued with Phlogiston.
Furina’s Pyro archon appearance:
She changed her outfit to Natlanese style and decorated it with elements from her OG outfit by cutting it up a bit. She changes her hat, and turns the droplet ornaments on her outfit into hairpins, attaching her hat’s dark blue side clothpieces to them. She keeps the shorts, but switches them off to a baggier one, and changes her little heels to knee-high boots. Her top is a simple dark-blue long-sleeved body that has a cleavage cut resembling Focalors’s golden beads.
When she uses the power of the Primal Fire, her hair sets on fire, and here’s the catch: her flames are blue.
Edit: her Nightsoul blessing forms a blue tiara-like halo around her head.
