Ahsoka escorts a group of younglings to Ilum, where they will learn from Yoda and undergo a crucial rite of passage: the construction of their lightsabers. They grapple with both physical and inner challenges as they face the dangerous task ahead of them.

As the younglings return from Ilum with Ahsoka, their ship comes under attack by Hondo's gang of pirates. The children must use ingenious and improvised traps to thwart the brigands.

When General Grievous launches a full-scale attack on the pirate base on Florrum, Ahsoka and the younglings fight side-by-side with Hondo and his pirates to turn back the Separatist forces.

Letting the Force guide him, Yoda voyages into the heart of the galaxy to an ancient world that is one of the wellsprings of the Force and the source of midi-chlorians. Yoda undergoes difficult trials administered by the Five Priestesses, mysterious Force-wielders who hold the secret to immortality.
