The lyrics I used were part of some Fan Festival coverage follow-up from Fernehalwes. Leaving out any information that might unintentionally serve as speculation fodder, he clarified that the meaning and origin of Eorzea's name has yet to be revealed. Because we have translations of the lyrics, but don't have the meaning of Eorzea's name, I take that to mean it's not part of "the saviors must perish."
