From the introduction: Deep in the Vast, the world of Enereth-7 is a seemingly impossible planet, the sole survivor of its former solar system. Sometime within the time lost to history known as the Gap, a black hole consumed the various worlds of the solar system. Only the divine intervention of the goddess Yaraesa stopped the disaster from claiming Enereth-7 and its sun. The Lady of Wisdom manifested various divinely powered markers across the surface of the world while gently using her power to protect Enereth-7 and its star from the black hole that threatened to erase it. Since that time, the world has spun between the warmth of a sun and the entropy of a black hole, held between warmth and utter destruction.
