This sketch cover by Michael Turner, depicting Aspen Matthews seated on a beach, rendered in his signature line-art style. This variant was part of a series of covers for the Prelude issue, each showcasing different artistic interpretations of the character.

In Fathom Prelude #1, the story delves into the early life of Aspen Matthews. The narrative follows young Aspen as she competes in the Seoul Olympics, where she astonishingly breaks the world record in swimming. However, her victory is overshadowed by allegations of blood doping, leading to her disqualification. Disheartened, Aspen shifts her focus to marine biology, setting the stage for her future adventures in the underwater world of the Blue.
