Well, I remember ages ago several of us here (including you Moose as I recall) had a theory that the gigas at least were the result of Allagan genetic engineering and were created as a source of slave labour... given what we now though that theory is given increasing weight. After all, they even made cloning of the spoken possible (*cough* Unei and Doga *cough cough*) so this idea of the beastmen being the result of bizzare Allagan experiments just rings true.

Alas, that then blows holes in my own old theory that the 'early tribes' who were the original settlers of Eorzea back in the very First Astral Era after the Age of the Gods ended were not the spoken races at all but were actually the beastmen....
