Ghirahim (Total War)

Ghirahim is the spirit that was sealed within the first prototype of the Master Sword created by Hylia and the Sages of Hyrule, and later becomes the weapon of the Druthulidi Demise.

The Return of Sulkaris
Ghirahim is the first spirit abducted from the Sacred Realm by the Goddess Hylia to bind within the Master Sword - the ultimate weapon to be used by her chosen knight Link. Unfortunately, Ghirahim doesn't stay bound to the sword, and as a result, he is discarded and imprisoned in the Wizzrobe Cathedral in Vigjaro while another spirit is captured and trapped in his place.

A Tale of Two Swords
In 175 AG, hearing word of Demise's campaign against Hylia and feeling abandoned by his creator in favour of Fi, Ghirahim breaks free of the Wizzrobe Cathedral in Vigjaro and offers his services and knowledge to Demise. Demise gives him command over the Moblins, and consolidates his forces on the Gerudo-Hylian Border. After successfully summoning the ghost of his champion Ganon to possess the Gerudo Prince Ganondorf, Demise orders Ghirahim to stay behind in the Gerudo Desert while Ganondorf brings the fight to the Kingdom of Hyrule.

After Ganondorf suffers a crushing defeat at the hands of the Hylians and the Darknut Legion, and with Ganon convinced that Demise, not the Hylians, has been responsible for all of the ruin that had been brought to the Moblins, he turns against Demise and Ghirahim and sides with the Hylians and Darknuts.

Demise and Ghirahim are attacked by the combined Hylian and Gerudo armies. Despite his power over both of the armies' soldiers, Demise is eventually confronted by Hylia and challenged to a duel. Demise, wielding Ghirahim, is overpowered by Hylia, but Ganondorf intervenes before Demise could be slain. Ganondorf takes the Master Sword from Hylia even though the weapon begins to burn his hands. He successfully manages to impale Demise and destroy him, and with his master dead, the prototype Master Sword is destroyed as well.

In-game
In the campaign, Ghirahim will hunt down Link, Hylia, Fi, and any of your sages as the game progresses. In addition, Ghirahim will be fully usable in any regular custom match.

Ghirahim (and his counterpart Fi) are the single most powerful units in the game, and act as veritable one-man (or genderless robot sword) armies.
