Gotta love how these things can have multiple meanings;

"Light and darkness were divided, sundered in fourteen", coming off the pre-history stuff, this could be referencing the entire passage of recorded history, all fourteen eras and the conflict of Light/Darkness within.
"To the seas she cast Her children, for fear of the Moon", perhaps referencing the events of 2.55? The Scions were split up, cast to the seas as it were. Two you could argue literally were, if you consider our two favorite exhibitionists time in the Lifestream. Then we have Minfilia running off because of something Hydaelyn told her. Hydaelyn seemed to directly want to send her somewhere else... Then you've got a bunch of our other allies who literally got on a boat and went somewhere else...
"For hate of the Star, to the seas He cast His doom.", perhaps referencing the end of 3.0, in which Zodiark/Elidibus sends "His doom" from the Moon; The Warriors of Darkness.
