Complete story — includes the ending
The Ghost crew scouts an Imperial air field where the TIE Defender Elite is being tested. Sabine hits upon the idea of stealing its flight data recorder to obtain the information the rebels need about the TIE, but unfortunately Grand Admiral Thrawn appears to witness a combat demonstration of the new fighter. Cornered, Sabine steals the fighter to get herself and Ezra to safety, but due to an installed kill switch the fighter ends up stranded in the hills of Lothal. While hiding the TIE's hyperdrive for later retrieval and then trying to evade the Imperial search parties, Ezra catches several unexpected glimpses of a white Loth-Wolf, a rare predatory species. Eventually, the Loth-Wolf appears before him, sends Sabine to sleep and carries them back to their friends, only to disappear as mysteriously as it appeared, leaving Ezra with the strange parting message "Dume" to ponder over.
