And that also brings in Fauxsefka and Iosefka being twins and detractors from Cainhurst. Honestly, I would not consider it too far stretch if Choir people simply were young physically. They are affiliated with Kin of Stars and Moon (celestial larvae and emissaries are called moon larvay and moon emissaries in internal files, and Ebrietas is straight up 'bastard of the Moon'). And Fromsoft likes adding theme of water's stagnation + flow of a river in their games... Marine and celestial Kin are very close to each other in this lore, one leans to another and they're both blue and tentacley, too. But especially whole natural thing of Moon pulling water! Even in Research Hall, when patients were delving into the Sea, they discovered leaning towards the stars with Milkweed, Lumenflowers and "actually we should go look into Isz instead".
