Everything has a beginning, even the death of history. When two novice Starfinders, the energetic Dae and somber Chk Chk, make a startling discovery, they unlock a link to one of the galaxy's most momentous events: the Gap, and the disappearance of the now lost world of Golarion. Shrouded in mystery, the Gap ended with mortals across the cosmos suddenly finding themselves with memories stripped from their minds without warning or explanation. The android Tyrcell wakes up on Absalom Station, the core of the Starfinder setting, on the day after the Gap. With their memories wiped, they contend with chaos on the station while surviving and building a coalition of memory-addled allies. All the while, other forces begin to wake after the cosmic event and enact plans of their own. From the undead media mogul, Zo!, who seeks to capitalize on the event, to the fiendish servants known as Hellknights, there's no shortage of opportunists as the galaxy reels! Both stories collide as the Starfinder agents and Tyrcell, separated by centuries, uncover a gift left to mortals by Yaraesa, goddess of knowledge and science. This secret could unravel the truth of the Gap, but in the days following the event, the nascent Hellknight Order of the Eclipse will stop at nothing to control exactly what that message is. Meanwhile, in the modern age, a mysterious figure trails the Starfinders as they follow in Tyrcell's footstepsFrom Hugo Award winning author Tim Pratt (City of the Fallen Sky, Reign of Stars, Liar's Blade) comes the definitive starting point to the science-fantasy galaxy of the award-winning setting of the Starfinder Roleplaying Game.
