In the future, mankind travels through space using vast spatial gates. A ship can be sent hurtling hundreds of light years in minutes. Despite the routine nature of deep space travel, things don’t always go so smoothly. Lost in the deepest depths of space, the Thunder Child has become the stuff of legends and deep space ghost stories – whispers in the night to scare new space travellers. When a signal is detected in a far off uninhabited and isolated solar system, believed to be the Thunder Child, the Horizon and her crew are tasked to investigate its disappearance and salvage her. As the crew embark on their journey, lead by the financial gains and fame that finding the fabled ship promises, they soon discover that some things are forgotten for a reason.
