Hi Myen'Tal I think abyssal is the wrong word to use in chapter 1.
The word abyssal refers to the deepest parts of the ocean, so the title 'An Abyssal Descent' is literally a descent to the bottom of the sea. Abyssal can also mean unfathomable/incomprehensible, but I doubt that you are meaning to say an 'Incomprehensible Descent'
Would I be right in thinking you are trying to say A Descent Into The Abyss, or maybe An Abysmal Descent?
Good luck with the second stage.
