The Drogheda Civil War represents a battle that unfolded on the planet of Drogheda during the era of the Galactic Civil War. After the Galactic Empire's loss at the Battle of Endor, the inhabitants of Drogheda started advocating for their own governance, with the goal of removing the reigning monarch, Queen Sarna. Sarna, enraged by this challenge to her authority, began suppressing the insurgents using her Royal Guard, commanded by Harlech. The downtrodden populace then coalesced into a unified rebellion, assisted by the queen's sibling, Danu. Danu, remaining inside the Drogheda Citadel, secretly intercepted governmental intelligence, providing critical support to her comrades. Eventually, the revolutionaries managed to seize control of the Mount Meru Mine, a crucial financial asset for Queen Sarna, thereby jeopardizing her capacity to finance her campaign against the rebellion. Seeking external assistance, Sarna enlisted the help of her previous romantic partner, Lando Calrissian, falsely asserting that the Empire was backing the rebellion. Calrissian arrived on Drogheda, but he quickly recognized the deception and chose to align himself with Danu and the revolutionaries. The rebels successfully attacked Sarna's stronghold, overpowering her royal guard and capturing the Queen. Following Sarna's capitulation, the revolutionaries compensated Calrissian to escort their former ruler into banishment away from Drogheda. Calrissian accepted, and the pair departed the planet. After they left, Danu announced that the people of Drogheda would endeavor to establish a new form of government, a democratic one.
