What is the rumbling aot?

The Rumbling in Attack on Titan (AOT) is a catastrophic event that involves the awakening of the Founding Titan, which has the power to control and command all other Titans. When the Rumbling is activated, the Founding Titan compels the Titans within the Walls to awaken and march towards the enemies of Eldia, trampling and destroying everything in their path.

The Rumbling is depicted as a last resort measure to protect the Eldian people from external threats, particularly from Marley and other nations that seek to destroy them. It is considered one of the most destructive events in the series, with the potential to wipe out entire civilizations and cause massive devastation.

Throughout the series, characters debate the morality and consequences of unleashing the Rumbling, as it comes with a high cost in terms of human lives and destruction. Ultimately, the decision to use the Rumbling becomes a central conflict in the narrative, as characters must grapple with the ethical implications of resorting to such extreme measures for the sake of survival.
