Timothy Zahn’s final installment of the intriguing Thrawn trilogy released today. Titled Thrawn: Treason, it completes the story of the intelligent Chiss tactician working his way up the ranks of the Empire’s military. The character of Thrawn was made particularly famous in the acclaimed Star Wars: Rebels television series. Author Zahn stated:

Thrawn often finds himself with additional struggles due to racism against the Chiss inside the Empire. He goes toe-to-toe with Director  Krennic and Grand Moff Tarkin. It’s a tale of political intrigue and manipulation set during the events of the final season of Rebels. At that time, Thrawn’s personal TIE Defender program is halted so the Empire can focus on Krennic’s Death Star project. Zahn elaborated:

As Thrawn focuses on his military career, his aspirations are interrupted when his former protege and assistant Eli Vanto tells him of trouble on his homeworld, forcing Thrawn to choose between the Chiss Ascendency and the Empire.

The character of Thrawn was originally introduced in Zahn’s Star Wars Legends series, the Heir to the Empire trilogy in 1991. Zahn said:
