So I've been reading a recent thread on Reddit about inter-racial couples in Hydaelyn, and someone brought up something that's been in the back of my head for awhile:

What exactly is the deal with Fyrgeiss's family?

Popokkuli, Seserukka and Nenekko - three Dunesfolk siblings, two twin brothers and one sister. The twins are referred to by dialogue and a journal entry in the Sunken Temple of Qarn (Hard) unlock quest as "the “sons” in Amajina & Sons Mineral Concern."

Now, I've no doubt they must be adopted if Fyrgeiss is meant to be their father, but the thing that gives me pause is this:

Emphasis mine. "The chairman's progeny"? This sounds more suggestive of actual offspring. Bizarre phrasing? Or are they not in fact part of Fyrgeiss's family at all, but the sons of the original "Amajina"? I know their mother, Shalala, also a Lalafell, appeared once in the 1.0 miner questline.

Fyrgeiss's Encyclopædia Eorzea entry doesn't mention the Lalafell youths at all, but instead tells us that he has three sons with names in the traditional Roegadyn tongue like himself. Have we ever met any of these sons? What's the deal here?

Anyone able to help me unravel this?
