Lewis, the lone crew member aboard a vast submarine, makes a living by harvesting a rare and mysterious mineral from the seabed in the Mariana Trench. The mineral's strange qualities make communication with the surface impossible. Utterly alone, surrounded by nothing but the watery void, Lewis will face an impossible dilemma. Lewis's tale will continue in Colossus Part 2.
