[ Hm. So even the Hydro Archon can't make much sense of the situation. He has no reason to doubt her authenticity as an Archon, so he simply takes her for her word. But what that does mean now, is that the entity that brought them here is certainly more powerful than an Archon, and is definitely within the range of a Descender. And given that the first Descender was the Heavenly Principles... their situation is looking graver and graver by the moment.

Ah, but Furina does point out something interesting. It's true that there are an abundance of individuals from Teyvat. However, he's a scholar, however unwillingly it is he takes that profession. ]

Though unlikely, it's not impossible that in a random sample of individuals taken from various worlds, a good number of them will come from the same world. There aren't enough people to determine if individuals from Teyvat were intentionally picked, or if this was truly random selection.

[ But perhaps by gathering information on all who are present on the ship, they may begin to form a hypothesis on what traits are being selected, if it is in fact, not random selection. From what he knows, of the individuals from Teyvat, three were Hydro users, and two—ah, wait. ]

I know of a fifth person from Teyvat. Venti the Bard, from Mondstadt. I encountered him a while ago. He is also an Anemo Vision holder.
