System Information
X:Y Coordinates -390.124 : 161.51[e]

The Ferihegy system was home to at least one world colonized through the use of sealed constructed habitats and as of 3145 was located in the Buena Province of the Lyran Commonwealth.[1][2]

System Description[edit]

The Ferihegy system is located near the Akfata and Kostinbrod systems.[1][2]

System History[edit]

The Ferihegy system was colonized at some point prior to the end of the Age of War.[3]

Political Affiliation[edit]

Planetary History[edit]

The Jihad[edit]

On the 4th of March 3075 agitators from the separatist Democracy Now movement bombed the Capital Arcology Complex on Ferihegy. The bombing killed more than 5,000 residents and resulted in a massive public backlash against the Democracy Now movement and its leader, Lindon Ashley.[29][30]

The capital arcology, Ferihegy Primus, had a population of some 63,000 people before the bombing, sheltered within the self-contained ecology protected by a six-sided pyramid constructed from ferroglass plates mounted over a steel-alloy frame. Key to the protection of the arcology were the flex points, designed to allow the frame and attached plates to adjust to expansion and contraction caused by heating while keeping the toxic atmosphere out at all times.[31]

The Democracy Now terrorists detonated fourteen charges in a sequential series that shattered flex points along the south face of the arcology. The explosives had apparently been placed on the outside of the structure, based on the trajectory of the resulting blast fragments, and destroyed entire sections of the ferroglass as well as fracturing the southern face of the arcology in several places. The explosions did the most damage to the zones of the city responsible for aeroponics and yeast production, and the initial explosion killed three hundred people, mainly agricultural workers, those involved in food production and maintenance personnel.[31]

The explosions caused an emergency network of bulwarks and locks to seal off the heart of the city, but between four and a half and five thousand more people perished from cyanide poisoning from the toxic atmosphere before the emergency measures succeeded in sealing off the remainder of the city. More damaging still to the viability of the ecology, was the loss of the vital zones responsible for feeding the population; two other ecologies on Ferihegy, Ferihegy Tet and Ferihegy Gamma, both pledged aid to Ferihegy Primus, while Ferihegy Geh, a new arcology still under construction, offered to provide free space and employment to any of the surviving citizens of Ferihegy Primus who wanted to relocate. Initial estimates indicated that the previously self-sufficient arcology would take four or five years to once again become self-sustaining.[31]

Lindon Ashley, released prerecorded messages on a number of worlds claiming that the attack would have been impossible in a state where the citizens were willing participants and supporters of the government, as such citizens would have fought to prevent the bombing; Ashley argued that the bombing had in fact only been possible because the citizens who witnessed the preparations for the bombing were so disenfranchised from the state that fatalism prevented them from interfering. However, casting doubt on this statement - a reiteration of many of the key points from previous speeches given by Ashley - was that the recording made no specific mention of Ferihegy or of explosions, suggesting that the message had been prepared in advance for use in the event of any major incident for which Democracy Now could claim credit.[31]


Ferihegy is a world with a toxic nitrogen-cyanide atmosphere that causes actively corrosive weather patterns. The human population of the planet lives in self-contained ecologies protected from the atmosphere.[31]

Planetary Locations[edit]

  • Ferihegy Gamma: an arcology on Ferihegy.[31]
  • Ferihegy Geh: an arcology under construction on Ferihegy during the Jihad.[31]
  • Ferihegy Primus: the capital arcology of Ferihegy.[31]
  • Ferihegy Tet: an arcology on Ferihegy.[31]


Ferihegy is most likely named after a district of Budapest, known for being the location of Hungary's major international airport.
