Triforce (Total War)

The Triforce, also known as Termina and on occasions as Tarm is a natural process of inhabited planets such as Hyrule and the Realm of Twilight.

Overview
In essence, the Triforce is a cosmic yolk encased in the material and immaterial world. When a physical body perishes, its soul enters the Triforce, and resides there indefinitely. While in the Triforce, or Termina, the soul sleeps and aids in the creation of a collective unconscious called Tarm (from the same root as Termina). When a Tarm grows to enough complexity and coherence, it wakes up, becoming an ego, and transforming the physical world hosting the Triforce into its own body. Depending on the relationship of the souls to the Creator, the newborn god becomes subject to either its own id or superego.

While dreaming, a soul is subjected to repeating the three worst days of their life endlessly. Sometimes, the three days will be anachronistic merges of several events in their life, and generally center around one's guilt and mistakes. The goal of a soul is to achieve enlightenment, also known as the fourth day, though according to Hylia, no soul has ever done so.

Primordial Age
Due to the influence of Majora, many Triforces fell to the increasing presence of Druthulidi. At least five of them fell during their creation, and Dethl is said to have drowned countless worlds in their nightmares. The Druthulidi Bellum eventually consumed the world of the Parella before being led to the homeworld of Zora, and later the Realm of Twilight.

Due to the opening of a portal between the Realm of Twilight and Hyrule, the former was able to connect to the latter and send its souls to its Triforce. In addition, it was able to remain habitable, though it's unclear whether this is because of Hyrule's influence or Bellum simply not eating everything.

According to the Book of Mudora, the Triforce was created by the Goddesses following the Druthulidi conflicts in order to give life to the world and maintain beings that would fight the Druthulidi and uphold the laws and desires of the Goddesses.

After its creation, the Goddesses left Hyrule and entrusted the Triforce to the First Sages, awaiting for the Firstborn of the Goddesses so that it may be passed on to mortals. One of them, Sulkaris, became corrupt and attempted to steal the Triforce, but was thwarted by the other Sages and banished from the Sacred Realm forever.

When the Firstborn of the Goddesses awoke into Hyrule, the six loyal Sages and the three Oracles passed the Triforce unto them and placed it in their care.

Oocca propaganda tells that Termina was created by Majora shortly after the creation of Hyrule when it arrived at the world, evidently in an attempt to mimic the Goddesses' act of creation. Enraged at the perverted version of their world, the Goddesses trapped Majora within its parallel world, threatening it with death should he ever directly manifest in Hyrule again. All of Majora's mortal worshipers were likewise trapped within the plane, doomed to repeat the 3 worst days of their lives for all eternity. In retaliation, Majora called its Druthulidi kin to Hyrule and set about twisting the creations of the Goddesses against their will. In reality, Termina already existed naturally.

Great Sea War
Shortly after the near extermination of Oshunites, Cobble, Lokomo and Parella, the majority of Ocean Zora are damned into Termina alive for unknown reasons.

Ancient Age
In 2994 BG, the Druthulidi Vaati successfully convinced Zalunbar, the ruler of the Darknut Legion, to form an alliance against the Wind Tribe and covet the Triforce in their care. The Darknuts then initiated a crusade against the Wind Tribe, nearly destroying their race. On the brink of extinction, the Wind Tribe decided to ascend to the heavens with their powers and leave Hyrule forever. With the help of King Gustaf and the Ancient Hylians, Vaati and his armies of Darknuts were halted long enough for Siroc and the last of the Wind Tribe to escape. With the Wind Tribe gone, the Triforce was passed unto the Kingdom of Hyrule.

For many years, the Triforce is kept safe in Hyrule Castle, the capital of the Kingdom of Hyrule, under the throne of the King

In 2993 BG, Majora successfully tempted King Igos du Ikana into inciting a 3-day civil war that tore apart the Kingdom of Ikana. Upon the conclusion, almost every Ikanian lay dead, and Majora absorbed the Kingdom and its Garo vassals into Termina alive. They would be doomed to repeat they same three days of civil war for almost 3000 years.

Rise of Ganon
In 1 BG, the Moblin King Ganon kidnaps Princess Nylin Zelda I, the daughter of the current King Daphnes Nohansen Hyrule. In order to protect the Triforce, the King moves it from Hyrule Castle to the Water Temple under Lake Hylia and puts it in the care of the Zora guards.

The Princess is eventually forced to reveal the Triforce's location by the traitorous Sheikah Bongo's Eye of Truth, and with this information Ganon launches a full-blown assault on Hyrule Castle. Though the city ultimately falls, Ganon fails to obtain the Triforce - his final goal. Before King Nohansen dies, Bongo is able to extract from him the new location of the Triforce, but she decides to lie to him that it's in the Fire Temple on Death Mountain, since she realises that he'll contest with her when the artefact is found.

While Ganon is misled to Death Mountain and later killed by the Hylians when they assault his new fortress, Bongo and her followers rush to the Water Temple, but they did not expect Twinrova's Gerudo and Veran's Fairies, who also learnt of the Kingdom's fall and the Triforce's new location, to arrive and contest with them on the artefact.

When the three armies are busy fighting each other, the Zora Dominion is able to send a battalion to Lake Hylia to help defend the Triforce, and with the help of Zelda, Rauru, Impa and Demise, they are able to secure the Triforce before either Bongo, Twinrova or Veran would be able to snatch it. Having failed in their quest, all three armies surrender to the Zora.

First Golden Age
Shortly after the defeat of Ganon, the Sage of Light Rauru convinces Mediator Ooccoo that keeping the Triforce in Hyrule is too dangerous and that it should be returned to the Sacred Realm as it was in ancient times. Claiming that keeping the Triforce locked away from the world would lead to a decline, Rauru proposes to create a portal that could be opened to the Sacred Realm in times of need and suggests converting the Temple of Time in Hyrule Castle Town into such a door. The Oocca agree and work with Rauru in secret to transform the Temple of Time into a portal to the Sacred Realm. Once completed, Rauru and the Oocca build the Temple of Light inside the Sacred Realm and bring the Triforce to rest there.

Gerudo Wars
In 100 AG, Vaati starts the Gerudo Wars in order to seek the Triforce for a second time, and for this goal he coaxes the Gerudo to declare war against the Kingdom of Hyrule. While the Gerudo successfully sacks Hyrule Castle Town, they are ordered by Vaati, Agahnim and Onan to immediately retreat so the Darknuts can occupy the city. Vaati and Agahnim search for the Triforce in Hyrule Castle Town, but both fail. Soon they are driven out of the city by Impa and the loyal Sheikah.

The Return of Sulkaris
During Sulkaris' anabasis and the abduction of the princess of Hyrule, Zelda has multiple visions centered around the Triforce and the war between the First Sages.

When Maphaeus is confronted by Sulkaris, she reminds her of what will happen if they let the Triforce run its course. However, Sulkaris replies that she intends to take the Triforce for herself.
