As several crises all hurtle toward their thrilling and shocking conclusions, fan-favorite Jedi Knights and Padawans must band together to save the galaxy from the Nihil, the Nameless, and perhaps worst of all, a mysterious blight that turns everything in its path to dust and is seemingly impossible to stop.

After a series of staggering losses, the Republic seems to finally have the villainous Nihil marauders on the run, and it looks like there's light at the end of the tunnel. Until word comes of a suspected Nihil attack on the industrial cosmopolitan world of Corellia, right in the Galactic Core. Sent to investigate are Jedi Masters Cohmac Vitus and Kantam Sy, along with Padawans Reath Silas and Ram Jomaram, all fighting their own private battles after months of unrelenting danger.

The Galactic Republic is in chaos following the Nihil’s shocking destruction of the gleaming space station Starlight Beacon. Capitalizing on their victory, the Nihil have erected a barrier called the Stormwall around a section of Republic space and claimed it for themselves. Within this Occlusion Zone, people live at the mercy of the Nihil—and the Nihil are not known for mercy.

Vernestra Rwoh is a new Jedi Knight at age 16, but her first real assignment feels an awful lot like babysitting. She's been charged with supervising 12-year old aspiring inventor Avon Starros on a cruiser headed to the dedication of a wondrous new space station called Starlight Beacon. But soon into their journey, bombs go off aboard the cruiser. While the adult Jedi try to save the ship, Vernestra, Avon, Avon's droid, J-6, a Jedi Padawan, and an ambassador's son make it to an escape shuttle, but communications are out and supplies are low.

It is an age of exploration. Jedi travel the galaxy, expanding their understanding of the Force and all the worlds and beings connected by it. Meanwhile, the Republic, led by its two chancellors, works to unite worlds in an ever-growing community among near and distant stars. On the close-orbiting planets of Eiram and E’ronoh, the growing pains of a galaxy with limited resources but unlimited ambition are felt keenly. The two worlds’ hatred for each other has fueled half a decade of escalating conflict and now threatens to consume surrounding systems.
