Battle of Zakuul

The Battle of Zakuul was the final engagement of the war against the Eternal Empire of Zakuul, after which the Empire ceased to exist. After the decisive assault on Odessen in which the Eternal Empress Vaylin was killed, the Eternal Fleet was left without a leader and reverted to its original function of exterminating all complex life in the galaxy. The Eternal Fleet warships began bombarding Dromund Kaas, several Core Worlds including Coruscant, and Zakuul, which was also blockaded to protect the Eternal Throne. Realizing that the Throne needed an occupant to keep the Fleet docile, the Alliance departed to Zakuul with their fleet, the Gravestone at its helm. Shield upgrades based on Iokath schematics allowed the Gravestone to breach the blockade and engage the Eternal Fleet, while the Alliance Commander traveled down to the surface along with Arcann and Senya Tirall. The three of them made their way to the Spire, receiving unexpected assistance from Indo Zal and his Zakuulan rebels, and eventually reached the Eternal Throne room. The Commander claimed the Throne, which pacified the Fleet, but immediately afterwards Valkorion revealed his ultimate goal to eradicate the Commander's mind and take possession of their body as his new vessel, shocking them into nothingness.

The Commander awoke inside their own mind, wearing Valkorion's form in a subconscious attempt to save their identity from being erased. Locating the mental image of Dramath's holocron, the Commander regained their identity, after which Valkorion manifested and summoned Vaylin's spirit, placing her under his spell and commanding his daughter to destroy the Commander. The Commander used the holocron to free Vaylin from her father's mind control, at which point Arcann has joined them inside the Commander's mind and convinced Vaylin to join them against Valkorion. All three of them attacked the Immortal Emperor, but Valkorion destroyed the holocron, claiming that nothing was able to stop him. However, since his spirit was now bound to Vaylin's and shared her weakness, the Commander used Vaylin's mental conditioning to turn the tables on Valkorion and weaken the Emperor for a killing blow, putting an end to his millennia-long existence. With the Immortal Emperor gone for good and the Eternal Fleet under their control, the Commander then proclaimed the age of the Eternal Alliance, unifying the military of Zakuul and the Eternal Fleet with the cause of the Alliance as a new galactic power.
