Nobody was happier than Ottley when Docky announced that Zero and Truen will spend the rest of their time training with him while the shipwrights finished the Marissa. Docky kept his students busy daily and often took them out to sea for a practical demonstration.
"Since the both of you can breathe underwater, swim and see things in the dark, you can start diving. I will explain as I go along with the diving sessions about the things to expect underwater. There are five basic layers under the sea, and each layer has its own dangers."
Very quickly, Docky explained that there were five layers of the sea, but the Marissa was only able to dive until the third layer, no deeper than that.
"Unlike the sunlight, twilight and midnight zones that the Marissa can sail in, the deeper levels are not fit for survival conditions. Sea monsters often lurk in the abyss layer, and some even reside deep in the trenches."
