An excerpt from the Booke of Mythical Creatures of Tzurann:

“A vast sea of darkness reached between the two lands of Lebah and Niak. Since long ago, this expanse of water had been known as the Arca, which in the common tongue, translates to the Ark. Legend has it that a fearsome aquatic beast with magnificent wings lived in the depths of the Ark, waiting for unsuspecting victims to cross its domain.

Its name, was Seargon.”
