Lore question! As a roleplayer I've enjoyed bits of lore SE has littered around but there's one thing that has eluded me... What were the races of each member of the Twelve?

Taken from Eorzeapedia.com

Nald'thal is the brother of Oschon. Oschon is the brother of Nald'thal, Menphina's lover, and the teacher of Halone.
Menphina is the sister of Azeyma, Oschon's lover, and the daughter of Althyk.
Azeyma is the sister of Menphina, Thaliak's lover, the daughter of Althyk, and the mother of Llymlaen and Nophica.
Thaliak is the teacher of Byregot, Azeyma's lover, and the father of Llymlaen and Nophica.
Rhalgr is the apprentice of Nymeia and the father of Byregot and Halone.
Althyk is the brother of Nymeia, the father of Menphina and Azeyma, and the grandfather of Llymlaen and Nophica.
Nymeia it the sister of Althyk and Rhalgr's master.
Llymlaen is the sister of Nophica, is the daughter of Azeyma and Thaliak, and is the grandaughter of Althyk.
Nophica is the sister of Llymlaen, is the daughter of Azeyma and Thaliak, is the grandaughter of Athlyk, and is rivals with Halone.
Byregot is the brother of Halone, the son of Rhalgr, and the student of Thaliak.
Halone is the sister of Byregot, the daughter of Rhalgr, the student of Oschon, and the rival of Nophica.
So as we see each of the Twelve were somehow connected with one another. Yet the question remains, why are they worshipped in Eorzea? And what were their races? The Twelve are considered the Gods of Eorzea, but were they the ones who created Eorzea or Hydaelyn for that matter? Are the Twelve believed in and worshipped all over Hydaelyn or only in Eorzea? Hopefully the dev team can dig up some more tidbits of lore for us on all this.
