As civil war between the Republic and the Separatists rages across the galaxy, nowhere is the fighting more fierce than on the swamp world of Drongar, where a beleaguered mobile hospital unit wages a never-ending war of its own....

The war that erupted in Star Wars: Episode II Attack of the Clones is nearing its boiling point. The Separatist forces continue their assault on the Republic as the diabolical triumvirate of Count Dooku, General Grievous, and their Master, Darth Sidious, fine-tune their strategy for conquest. Capturing Trade Federation Viceroy and Separatist Councilmember Nute Gunray is the mission that brings Jedi Knights Obi-Wan Kenobi and Anakin Skywalker, with a squad of clones in tow, to Neimoidia.

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.

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 Separatist Alliance, with ruthlessness and treachery, is beating the Republic to every strategic target. But after a costly clash with General Grievous for the planet Kothlis, Anakin has a mission that will focus his anxious mind. Alongside Obi-Wan Kenobi, he is posing as a long-lost native of Lanteeb, an impoverished world on the Outer Rim. This seemingly unimportant planet has drawn the interest of the Seps and Anakin, and Obi-Wan soon discover the disturbing reason.
