Yogar Lyste is a human Imperial lieutenant from Garel, voiced by Liam O'Brien in Star Wars Rebels from the 2014 pilot film. As Supply Master on Lothal he was responsible for imports, exports and local security, and he was comprehensively out-thought by the Spectres — most memorably when they made off with three Hammerhead corvettes from under his guard.
His usefulness to the story is as collateral. Agent Kallus, secretly the rebel informant Fulcrum, swapped code cylinders with him, persuaded him that Governor Pryce was the traitor, and let rebel operatives use his credentials to board Thrawn's flagship. Lyste was arrested as Fulcrum and faced execution. Thrawn privately suspected the truth and publicly accepted the frame anyway, which tells you most of what you need to know about Imperial justice.
