Here is a little information on some of the Core Fifty worlds.
Adrastos is a industrial center under the URE banner located in the 13 Eridani system that produces war materials for the UNSC with a population of 304 million citizens. It is also known for being along at least fifteen trade routes making it a commercial hub with a 98 vessel-strong task force defending it. Adrastos was the 15th closet colony world to Earth, was colonized in 2389 by immigrants from the United Republic of North America, Greater Czechoslovakian Authority, and the Federal Republic of Germany. The planet's has a booming economy with manufacturing, private, tourism, and agriculture sector with a GDP of 86 billion UN credits per year. It had at least fifteen space elevators connecting to orbital ports in orbit of the colony. Many companies like SinoViet Heavy Machinery, Traxus Heavy Industries, Cross Interstellar, and White Star Cruise Lines and Trade Corporation have a massive amount of facilities. Unfortunately Adrastos fell to the Covenant in 2548 after a seven-month long siege ending with the UNSC evacuating most of the population and moving most of it's industrial assets to Taradia (Mid-Rim), Beta Hydri VI (Mid-Rim), New America (Core System), Barrow (Inner-Rim), Tribute (Inner-Rim) and other worlds like it. In 2550, the UNSC 3rd and 8th Fleets had returned to Adrastos and dealt a crushing defeat to the Covenant Fleet of Indulgent Fury nearly wiping them out at cost of five dozen 8th Fleet vessels with the 3rd Fleet losing roughly 23 ships and 60,000 Marines KIA or MIA. In 2554, many refugees that were or could trace that were from the colony, returned to Adrastos after Cross Interstellar and Traxus Heavy Industries used Forerunner terraformation technology found on Sangheilos and Concord to reterraform the areas that glassed during the First Adrastos Campaign with the colonial population believed to return to pre-2548 levels in 2568. The Federal Republic of Adrastos' citizens are called Adrastonians or Adrastians. This is a highly independent colony with a large voice in the URE Congress and a large tourism sector, only two of many things that Adrastonians and other humans across the URE territory love about this colony world.
The inner colony of Barrow is a Earth-like planet under the administration of the URE with a population of over 504 million citizens. Barrow was colonized in 2389 by immigrants from the United Kingdom, former members of the British Commonwealth like Australia and the Falklands, URNA, and the Federal Republic of Korea. Barrow possesses a highly diverse economy, agriculture, industrial manufacture, and a growing services sector with a annual GDP of 94 billion UN credits, the fourth highest after Reach's 95 billion UN credits per year, Paris IV's annual 96 billion UN credits, and Earth's yearly GDP of 99 billion UN credits. Like its namesake, Barrow's largest industry was its shipbuilding sector, which was dominated by Harland and Wolff's orbital construction yards and the majority of this construction was conducted planet-side with orbital elevators carrying components and 'blocks' to the orbital yards. Materials and components for this construction came from both the planet's own plants and from other colonies in bulk freighters. These shipyards are also responsible for building UNSC fleet vessels alongside Reach, Mars, New Carthage, Taradia, New Korea, and many other colonies that have shipyards capable of maintaining companies like Oros Trading Company or the UNSC Navy's fleets. Barrow, unlike some of the mentioned colonies, survived the the Great War unscathed. Another interplanetary defense company BAE Systems maintained a large factory, located near the capital city of New Columbia, that produces component parts for aircraft, most of which would undergo final assembly on Reach. After Reach was glassed and abandoned in the summer of 2552, BAE Systems moved final assembly facilities to Sedra, Taradia, Concord, and several other locations across Earth and Her Colonies, and would reestablish their Reach facility in 2555 after the recolonization of the fortress world began. Barrow was location of UNSC 4th Fleet's headquarters and where the majority of said fleet was based out of. URE citizens from Barrow are known Barrovians, who pride themselves on their shipbuilding capabilities and industrial might while maintaining a environmental balance. Barrow is also fiercely loyal to the United Republic of Earth and Her Colonies.
Miridem is a major colony located in the Zeta Lupus system. In 2549, the UNSC evacuated and abandoned Miridem in response to the glassing of Arcadia, fearing that Miridem and its remaining inhabitants will suffer the same fate. After the war, a Covenant remnant faction set up shop on Miridem and it's neighboring colony of Wolff coming into conflict with a large group of New Colonial Alliance troops and mercenaries that also came hoping to find anything valuable left behind. The NCA hoping to find anything that could be of use to them and the mercenaries want to sell anything valuable on the black market. The conflict came to an end in 2554 when the UNSC launched Operation: IRON WILL to reclaim colonies lost to either the Covenant, fell under Insurrectionist control, or were just abandoned during the war. The UNSC 3rd Fleet and elements of the 4th Fleet arrived with the intention of taking the colony back. After two months of fighting Miridem was once again back in UEG hands, with reverse engineered Forerunner terraformation tech being used on the glassed areas of the colony.
AN: Recent information released by GrimBrotherOne reveals that Andesia is controlled by a mega-corporate council that is highly resented by the colony's citizens for it's excessive control on the planet's populace which led to the Insurrectionist activity (that lasted from 2523 to 2533) that resulted in the death of Cadmon Lasky and his squad, it was only the Covenant threat that caused the armistice between Andesian Insurrection and the UEG, but with end of the Covenant War in 2553, tensions threaten to break out into civil war.
GrimBrotherOne has released some rather interesting and somewhat mysterious information regarding Gannick 22, an inner colony world located in the Gannick system mentioned in Halo: Nightfall, which is called by Horrigian as being a major population center in human territory as it had survived the Human-Covenant War unscathed. Gannick 22 was named after the original twenty-two scientists and pioneers of the exploratory vessel UNSC Gannick arrived at what would become a heavily populated Inner Colony in between 2362 and 2390. These original colonists perished exploring the planet's once-hostile environment and humanity would honor them by naming the planet Gannick 22. The Have S'Moa restaurant and petting zoo owned by entrepreneur Wiljax Brantley, located on Inner Colony world of Gannick 22 and is currently have the largest Moa population after Reach fell (due to the majority of Moa being wiped out with only some in living remote sectors of the planet that was not glassed by the Covenant), the rest became popular right after the war and Moa nuggets are quite the expensive delicacy among wealthy UEG officials.
What had happened to the crew of the UNSC Gannick really, did they find Forerunner ruins and encounter a rampant Monitor that killed most of them via Sentinels before the sole survivor found a Forerunner weapon with enough firepower to destroy it, and did survivor's guilt get him or her that made them commit suicide? PM me or type down your idea in a review.
Chi Rho is also known as Terra Prime for it's Earth-like surface. One of Concord's moons looks like it is home to a large city or a station.
