THE GREAT ENCLAVE in STARFIELD
Back in the day, the Fallout series was a huge success for Bethesda Game Studios, contributing their development of their newest game, Starfield.
Starfield is seen as a wider expansion of its story to the Fallout series, as the game takes place in 2330, 43 years after the events of Fallout 4.
Since its foundation in 2067, The Great Enclave (commonly referred to many as The Enclave) remained an industrial, economic, political, diplomatic, and military superpower in the Settled Systems, outnumbering the rising Brotherhood of Steel and the United Colonies.
Since the release of Starfield, there is a much more positive theory suggests that the Great Enclave maintained its larger presence in Akila and Volii systems in the Settled Systems after the partial destruction of the planet Earth caused by the Great War of 2077 (1787 AD) and its complete destruction in the year 2155 (1865 AD).
Starfield is offically being the true sequel to the Fallout series, which takes place in the 2330, 43 years after the events of Fallout 4.
Starstation Eden, located in Akila System and Richardsonville in the planet of Akila, were served both the joint the capitals of the Great Enclave.
The current President of the Great Enclave is Elizabeth Autumn, who was Augustus Autumn's great-granddaughter.

HISTORY OF THE GREAT ENCLAVE
In 2067, the political uncertainty of the United States led to the creation of the First Enclave by the US President Thomas Eckhart and he later becoming the First President of the Great Enclave.
In September 2077, a month before the Great War, the Enclave moved to capital city to Cydonia in the planet of Mars, which was overtaken by the United Colonies in 2170.
Around the year 2167 (1877 AD), the Second Enclave came into existence around the Volii system, as they are the biggest ally to the United Colonies. The Enclave's capital city, Great Poseidon, was built between 2070 thrugh 2076, as she only made Enclave's official capital by October 20, 2077, three days before the Great War.
As the First Enclave existed from 2067, the United Colonies-aligned Second Enclave was founded in 2160 (1870 AD) around the Station Poseidon II near Volii Alpha in Volii System.
By 2159, the United Colonies (or the UC) was declared independence the Great Enclave. This resulted the relocation of Great Enclave's government from Solar System to Cheyenne System.
Its capital city outside Great Poseidon is Richardsonville in Akila, located 200 miles away from Akila City, which was founded in 2167 (1877 AD). Situated in Akila, Richardsonville was also the capital city of the Great Enclave since 2170.
The year 2267 saw the unification of the First Enclave of the Cheyenne system and Second Enclave of the Volii system into the Great Enclave under president John Henry Eden of the First Enclave. This result of unification was caused by the deposition of Richard Richardson Jr through a military coup led by Augustus Autumn, who became the de jure President of the Great Enclave in 2277 (as well as John Henry Eden's successor). Both Autumn and Eden were the central figures behind the unification.
Starstation Perseus (capital of Volii Enclave) later merged into Starstation Poseidon (capital of Akila and Sol Enclave) in 2267 to become Starstation Eden, named after John Henry Eden. It remains the capital of the Great Enclave since its 2267 unification through Augustus Autumn's military coup against Richard Richardson Jr and Jonathan Maxson's leadership with the First and Second Enclaves.
After its 2307 collapse, another Great Enclave ally, The Institute in the Boston Commonwealth is merged into Ryujin Industries.
The presidency of Augustus Autumn from 2277 through 2310 faces their uncertain future against their once-friendly diplomatic ally, the Brotherhood of Steel.
In 2310, toward the end of the Colony War, the United Colonies backs William Coulson's coup d'etat against Augustus Autumn, which resulted in Coulson's 18-year presidency and his subsequent alliance with the United Colonies.
John Henry Eden Spaceport in Richardsonville provided the regular space flights to Alpha Centauri, Porrima, and Volii systems from Akila, Cheyenne system.
The Inter-Eden is a flag carrying space flyer for the Great Enclave, which was existed since 2170.
The Great Enclave remained an industrial, economic, political, diplomatic, and military superpower in the Settled Systems, outnumbering the rising Brotherhood of Steel and the United Colonies.
Its current President, Elizabeth Autumn, maintains her friendly relations to the United Colonies, Freestar Collective and the Brotherhood of Steel. She was also the second Great Enclave President to having her faith within the House Va'runn, the first being Augustus Autumn.

Unification, John Henry Eden and Augustus Autumn-era (2267-2310)
By 2267, the First Enclave and Commander Augustus Autumn staged his military coup against Richard Richardson Jr, deposing him and culminating the unification of Second Enclave (under President Jonathan Maxson, father of Supreme Elder Arthur Maxson), forming Great Enclave. Augustus Autumn had being a distinction of a military commander of the First Enclave with his religious ties with House Va'runn and the Great Serpent.
That same year, the UC evacuated the remaining Enclave citizens to Alpha Centauri system and the exiled Enclave citizens proving a safe heaven in New Atlantis. The UC later declares the war on Great Enclave against John Henry Eden and Augustus Autumn, who had being a follower of House Va'runn and the Great Serpent.
By 2277, 10 years after he unified First and Second Enclaves under the guidance of John Henry Eden, Augustus Autumn became the 5th President of the Great Enclave. The United Colonies welcomed his leadership through his role in unifying the two Enclaves to form Great Enclave, the legitimate successor state of the First Enclave.
By 2280, the UC recognized the Great Enclave as the unified successor state of the First and Second Enclaves.
By 2328, Autumn died peacefully in his sleep and his great-granddaughter Elizabeth Autumn succeeds him as the next President of the Great Enclave.

Augustus Autumn's administration within the Great Enclave has been characterized in several key factors during his 51-year term (2277-2328);
- The unification of First and Second Enclaves in 2267 leading the formation of the Great Enclave. This result caused by Autumn's overthrow of both Jeremy Maxson of Volii Enclave and Richard Richardson Jr of the First Enclave through a military coup.
- His interrupted diplomatic relations with both the Brotherhood of Steel and the United Colonies led to the Brotherhood-Enclave War (2267-2280)
- After the Great Enclave restored its diplomatic relations with both the Brotherhood of Steel and the United Colonies in 2280, President Autumn oversaw the coronation of His Majesty Supreme Elder Arthur Maxson of the Brotherhood of Steel in 2283 at Starstation Cygnus following the 2282 passing of his successor Owyn Lyons.
- In 2307, President Autumn aligned himself with his religion of House Va'runn and the Great Serpent, culminating his alliance with Freestar Collective and the outbreak of the Colony War, prompting the UC to declare war against the Great Enclave and Freestar Collective.
- In 2310, during the destruction of Londinion by the Terrormorph invasion, Augustus Autumn was overthrown by William Coulson in a United Colonies-backed military coup. Coulson became the Great Enclave's next president shortly after his successful coup against Augustus Autumn.

William Coulson-era (2310-2328)
In 2310, amidst the destruction of Londinion on planet Toliman II on the hands of the Terrormorph invasion, 29-year old William Coulson, a high-ranking Colonel of the Great Enclave Army, launches a violent coup d'etat backed by the United Colonies, against the brutal Presidency of Augustus Autumn. He suceeds, and Coulson himself became the President of the Great Enclave, culminating the end of President Augustus Autumn's 33-year brutal rule and Coulson's alliance with the United Colonies to defeat the Freestar Collective, Crimson Fleet, and House Va'runn.
In 2311, following the Battle of Cheyenne, President Coulson signs an armistice treaty with the UC, Freestar, and Brotherhood of Steel, ending the Colony War and bringing the fragile peace.

Elizabeth Autumn-era (2328-present)
In 2328, after Coulson's resignation, the Great Enclave begins their new era with Elizabeth Autumn assuming her power as the President of the Great Enclave following the death of her great grandfather, Augustus Autumn. The period of transition to democracy marks a new chapter for the Great Enclave.
In 2330, the United Colonies (UC) marks its 50th anniversary of the diplomatic recognition of the Great Enclave in Akila City, with UC President Alexandra Abello and Great Enclave President Elizabeth Autumn in attendance.
