The skaa rebellion is the underground resistance movement fighting against the Lord Ruler's thousand-year reign over the Final Empire. The skaa - the oppressed lower class, kept in near-slavery by the nobility - have attempted uprisings before, but all have been crushed with overwhelming force. The rebellion operates in secret cells across the empire, coordinated by leaders like Yeden, who serves as its figurehead during the events of The Final Empire. Kelsier's plan to overthrow the Lord Ruler gives the rebellion its first real chance at success, combining Allomantic power, strategic deception, and the rallying symbol of the Survivor himself. The rebellion's army, trained by Ham and funded by the crew's stolen wealth, ultimately plays a decisive role in the fall of Luthadel - though the victory comes at a cost far higher than anyone anticipated.
