The Tarkin Massacre devastated the planet of Ghorman more than a decade before Andor. LucasfilmIn the non-canon Legends timeline, the Ghorman Massacre occurred when Grand Moff Tarkin landed a transport on the planet of Ghorman despite a peaceful protest happening below. In Andor, we learned this event did in fact happen 16 years ago, but it’s not known as the Ghorman Massacre. Andor’s version of the Ghorman Massacre was similar to the previous event that so many of the citizens remember, but with a few key differences. But once everything goes down, the false-flag operation reaches a new level: the Ghorman citizens, despite everything, are peaceful — just singing their anthem in the plaza.
