On the planet Tython, the ancient Je’daii order was founded. And at the feet of its wise Masters, Lanoree Brock learned the mysteries and methods of the Force - and found her calling as one of its most powerful disciples. But as strongly as the Force flowed within Lanoree and her parents, it remained absent in her brother, who grew to despise and shun the Je’daii, and whose training in its ancient ways ended in tragedy. Now, from her solitary life as a Ranger keeping order across the galaxy, Lanoree has been summoned by the Je’daii Council on a matter of utmost urgency.

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.

Obi-Wan Kenobi has not been apprenticed long to Qui-Gon Jinn, and he is chafing at Qui-Gon's training style: all meditation, no action. Obi-Wan yearns to prove himself on a mission, but when he and Qui-Gon are finally set to leave on an assignment, Qui-Gon is nowhere to be found. Angered by his master's abandonment, Obi-Wan sets out on the mission alone, determined to prove himself. On a mysterious planet he encounters a pack of feral, Force-wielding teens who seem to be the planet's only inhabitants.

It is a golden age. Intrepid hyperspace scouts expand the reach of the Republic to the furthest stars, worlds flourish under the benevolent leadership of the Senate, and peace reigns, enforced by the wisdom and strength of the renowned order of Force users known as the Jedi. With the Jedi at the height of their power, the free citizens of the galaxy are confident in their ability to weather any storm But the even brightest light can cast a shadow, and some storms defy any preparation.

The overthrow of the Republic is complete. The Separatist forces have been smashed, the Jedi Council nearly decimated, and the rest of the Order all but destroyed. Now absolute power rests in the iron fist of Darth Sidious–the cunning Sith lord better known as the former Senator, now Emperor, Palpatine. But more remains to be done. Pockets of resistance in the galaxy must still be defeated and missing Jedi accounted for . . . and dealt with.
