The Fallen Kingdoms of the Abyssal Plain

Tribal creation myth and folklore from the Northern Hemisphere, dating from 650 B.T.C. (Before the Third Cataclysm), Antediluvian Calendar:

Hearken, children of the Ersatz gods, sons and daughters of the New Earth, for here is truth. Long ago, before the third of Earth's moons fell fiery from the star-seared sky, there were those whom we have come to call the First Ones.

Those grand bioluminescent cities are now long since fallen, razed and dispersed, given over to the cruel whims of the unforgiving oceans. From the lore of our ancestors, we know the true nature of the cosmos. We know of the hidden and silent places, the places which reside in between the veils of reality, the places which mankind was never meant to see. All this we know… we who survive, we who are descended from those First Ones, and who give thanks to the gods-who-are-not-gods, for our creation, our genesis, for the breath of life that was forced into our progenitors during the early epochs of this cratered globe. Hearken, children of the Ersatz gods, sons and daughters of the New Earth, for here is truth…
