Operation: Thunderstroke was the code name for a mission sanctioned by Imperial Regent Morlish Veed that involved ambushing a secret meeting scheduled between exiled Galactic Emperor Roan Fel and members of the Jedi Order. Led by Moffs Rulf Yage and Fehlaaur'aitel'loro aboard the War Hammer, the Imperials' primary objective was to capture Fel, so that he might stand trial and be sentenced to execution, effectively ending the resistance movement of his exiled forces.
