Quick clarifications for those who don't understand: The Deep=the Darkness The Sky=the Light The Leviathan=an ancient Guardian of the Light. (A good Ahakmara?) The Worms=ancient followers of the Darkness. (Bad Ahakmara?) Fundament=Oryx's home"world." The remains of a solar system consumed within a gas giant. (When it references "diving" or the "storms above" this is speaking of the atmospheric layers of said gas giant. Oryx's continent, and indeed, every continent, floats on an upper layer of the giant.)
