"My job is to protect the Ascendancy and the Chiss people…
Whatever it costs to achieve that goal, I will pay it.
―Senior Captain Thrawn, and the back cover blurb[src]

Thrawn Ascendancy: Lesser Evil is a canon novel written by Timothy Zahn as the sequel to Thrawn Ascendancy: Greater Good, and the final volume of Star Wars: The Ascendancy Trilogy. It was published by Del Rey on November 16, 2021 along with its audiobook adaptation.

Publisher's summary[]

The fate of the Chiss Ascendancy hangs in the balance in the epic finale of the Star Wars: Thrawn Ascendancy trilogy from bestselling author Timothy Zahn.

For thousands of years The Chiss Ascendancy has been an island of calm, a center of power, and a beacon of integrity. Led by the Nine Ruling Families, their leadership stands as a bulwark of stability against the Chaos of the Unknown Regions.

But that stability has been eroded by a cunning foe that winnows away trust and loyalty in equal measure. Bonds of fidelity have given way to lines of division among the families. Despite the efforts of the Expansionary Defense Fleet, the Ascendancy slips closer and closer toward civil war.

The Chiss are no strangers to war. Their mythic status in the Chaos was earned through conflict and terrible deeds, some long buried. Until now. To ensure the Ascendancy's future, Thrawn will delve deep into its past, uncovering the dark secrets surrounding the ascension of the First Ruling Family. But the truth of a family's legacy is only as strong as the legend that supports it. Even if that legend turns out to be a lie.

To secure the salvation of the Ascendancy, is Thrawn willing to sacrifice everything? Including the only home he has ever known?[1]


The dramatis personae section of Thrawn Ascendancy: Greater Good, Lesser Evil's April 2021 predecessor, listed Mid Captain Ufsa'mak'ro as a cousin within the Ufsa family.[7] The dramatis personae of Lesser Evil lists Samakro as an Ufsa merit adoptive,[8] as did both novels' 2020 prequel Thrawn Ascendancy: Chaos Rising.[9]

In chapter 10 the Springhawk is twice called the Grayshrike.

In chapter 26 the Springhaw's helm officer, Tumaz'mor'diamir, is twice called Evroes'ky'mormi, who is the Vigilant's weapons officer.

In chapter 28 Thrawn is noted as a merit adoptive. However, in Memories 13 of Chaos Rising he was made a trial born,[9] and the dramatis personae of Greater Good and Lesser Evil lists him as a trial born.

  4. The events of Thrawn: Alliances set during the Clone Wars take place after the trial and exoneration of Ahsoka Tano. Star Wars: Galactic Atlas dates both the end of the the Clone Wars and the trial and exoneration of Ahsoka Tano to 19 BBY. As some of the events in Thrawn Ascendancy: Chaos Rising take place concurrently with Thrawn: Alliances, they must therefore take place around the year 19 BBY. Furthermore, Thrawn Ascendancy: Lesser Evil establishes that the attack on Csilla, which was depicted in Chaos Rising, took place "last year." Therefore, the events of Lesser Evil must take place around 18 BBY.
  5. Thrawn joined the Mitth family, entered Taharim Academy, and met Al'iastov and Thrass around 39 BBY per the following reasoning.
  6. The flashbacks in Lesser Evil occur prior to the main events of Thrawn Ascendancy: Chaos Rising, which are set around 19 BBY per the reasoning here.
