Ghirahim's Forces

Ghirahim's Forces is a faction from the Era of Skyloft that appears in Hyrule Warriors and Hyrule Warriors Legends. It is lead by the Demon Lord, Ghirahim.

The Demon King's War
Ghirahim's Forces were originally the army of monsters and demons lead by the Demon King, Demise who sought to obtain the Triforce, a divine artifact left behind by the Golden Goddesses. Under the Demon King, they plunged the land in darkness and bloodshed. They where opposed by the Goddess Hylia who protected the Triforce from evil. Hylia gathered the surviving Hylians and used her divine power to raise several land masses up into The Sky, with the largest becoming the land of Skyloft, while she herself remained on The Surface to fight the Demon King and his army, supported by the Gorons, Ancient Robots, Mogma, Kikwi, and Parella that remained on the Surface. Eventually, Demise was defeated and sealed within the Sealed Grounds by Hylia. The remnants of Demise's army rallied under the leadership of Demon Lord Ghirahim, the demonic spirit of Demise's Sword. Under Ghirahim's leadership, it sought to free the Demon King. Meanwhile, their archenemy Hylia created the Goddess Sword and its spirit Fi, before giving up her divinity to be reborn as a Hylian on Skyloft.

The Era of Skyloft
Hylia would be reborn as a Hylian girl named Zelda, the daughter of Headmaster Gaepora of the Knight Academy and best friend of a promising young academy student named Link. Unaware of her connection to the Goddess, Zelda would pulled down to the Surface by a cyclone created by Ghirahim while she was flying with Link after the Wing Ceremony. Ghirahim's Forces would have captured Zelda, were it not for the intervention of the Sheikah Impa, who Hylia had entrusted to protect her reincarnation. Meanwhile, Fi would reveal to Link that he was the Goddess' chosen, Hero and her master, destined to wield the Goddess Sword. At the behest of Gaepora and Fi, Link descended to the Surface to find his lost friend and discover his destiny. From Impa, Zelda learned of her destiny as the Spirit Maiden and under Impa's protection journey to the Skyview and Eldin Springs to purify her spirit, while being hunted by Ghirahim and his forces. However due Impa, Link, Fi's interference Ghirahim and his forces were unable to capture Zelda and together with Impa, Zelda managed to flee through the Gate of Time to the past. Ghirahim and his forces would continue to hound Link during his quest to find the Sacred Flames and prevented The Imprisoned Demon King from escaping its seal. Eventually, Link uses the power of the Triforce to destroy The Imprisoned by crushing it with the Statue of the Goddess. However Ghirahim manages to kidnap Zelda and reveals he plans to use her to revive his master in the past. Ghirahim succeeds in reviving his master and transforms back into Demise's Sword. However Link defeats Demise using the Master Sword forged from the Goddess Sword. Defeated, Demise places a curse on Link and Zelda, vowing that his hatred and the curse of the Demon tribe will be reborn in a cycle without end as it evolves, cursing those with the bloodline of the goddess (Zelda and the Royal Family of Hyrule) and the spirit of the hero (Link and his various incarnations). After Demise's body dissolves, his residual consciousness is absorbed into the Master Sword before the weapon is sealed away so the fiend can completely dissolve over time. Demise and Ghirahim's defeat sparks the end of Ghirahim's Forces. However Demise's hatred and the Demon Tribe's curse would continue to plague the land for centuries to come through the King of Evil, Ganondorf/Ganon.

War Across the Ages
As a result of Cia's use of the Triforce to warp time and space, in order to free the King of Evil's Spirit Fragment sealed inside the Sealed Grounds in that Era. This causes the Gate of Time inside the Temple to be transformed into a Gate of Souls which summons countless monsters into the Era of Skyloft.

The Demon Lord's Plan
Sensing the changes going on in her timeline, Fi descends to Sealed Grounds to stop Ghirahim and his forces from freeing The Imprisoned. In addition to Fi, Ghirahim's Forces are confronted by a Hylian girl named Linkle and her army of Cuccos, who come to Fi's aid.
