The Chertan system was home to at least one habitable world, Chertan I, and as at 3145 was located in the region of the former Republic of the Sphere known as the The Remnants or the Republic Remnant.[2][3]

System Description[edit]

The Chertan system is located near the Dubhe and Wing systems[2][3] and consists of a class A3V primary orbited by three worlds, of which the innermost world, Chertan I, is habitable.[1]

System History[edit]

The Chertan system was colonised during the First Exodus from Terra.[4]

Chertan I is the first planet in the Chertan system and has two moons named Osei and Pelipa.[1]

Planetary History[edit]

Chertan was originally settled to capitalize on the large amounts of mineral and metal resources. Despite being water poor, the presence of these natural resources allowed mining, smelting, refining and manufacturing operations to thrive. The citizens would export heavy machinery and metals and use the profits to purchase food from nearby agricultural worlds. This balance lasted until after the fall of the Star League.[1] The Free Worlds League annexed Chertan in 2783, one of the first of almost a score of Terran Hegemony worlds that the League would occupy as the Hegemony collapsed but before the First Succession War began.[5] Located close to the Lyran Commonwealth, Chertan was frequently targeted by LCAF raids. These raids left the world covered in scars, and damaged the few farms capable of feeding the population. Starving citizens rioted several times, and eventually the noble ruler was deposed in 2820.[1] Chertan had been a mighty industrial center under the Terran Hegemony, but the First Succession War reduced the standard of living to subsistence level.[6] By the time of the Jihad the world had lost its heavy industry as most companies relocated to more habitable planets.[1]

Chertan was occupied by the Word of Blake during the Jihad, and incorporated into the Word of Blake Protectorate; forces operating under the command of Duchess Alys Rousset-Marik liberated Chertan in January 3078 as a part of Operation SCOUR.[7] Chertan was one of four worlds to be hit simultaneously by forces operating on the Free Worlds League front of SCOUR on the 3rd of January; the First and Second Chertan Protectorate Militia Divisions struck at the Com Guard Fourth Army almost as soon as the Com Guard forces had made planetfall, and nearly succeded in forcing the allied coalition forces back off the planet. Ultimately, the greater experience possessed by the 4th Army carried the day, with the Com Guard forces pushing the Protectorate Militia Divisions back until their position became impossible to defend, leading to them surrendering.[8]

With only a sixth of the surface of Chertan covered by water, the geography of Chertan is defined by the name and location of the various large water bodies rather than by continent. Chertain has three large bodies of water: the Eerie Sea, the Huron Sea and the Ontario Sea. The Eerie Sea is the northernmost of the three, while the Huron Sea is located in the southern hemisphere.[1]

Planetary Locations[edit]

  • Altonia: third largest city on Chertan, located near the eastern edge of the Ontario Sea.[1]
  • New Pittsburgh: the second largest city on Chertan, located near the Eerie Sea.[1]
  • Theleopolis: the planetary capital city, located just south of the Huron Sea.[1]

Industrial Centers[edit]

  • Arista Chemicals: largest mineral mining and refining operation on Chertan in the thirty-second century; located in Altonia.[1]
