Spectral class F0V[1][2]
Recharge time 171 hours[1][2]
Recharge station(s) Zenith, Nadir[1][2]

The Donegal system was home to at least one habitable world, Donegal IV, and as at 3145 was the administrative capital of the Donegal Province of the Lyran Commonwealth.[3][4] Prior to the formation of the Lyran Commonwealth Donegal was the capital of the Protectorate of Donegal.[5]

System Description[edit]

The Donegal system is located near the Cameron and Gibbs systems[3][4] and consists of a class F0V primary orbited by at least four planets. During the thirty-first century recharge stations were in place at both the nadir and zenith jump points.[1]

System History[edit]

The Donegal system was settled during the First Exodus from Terra.[6]

Donegal IV - more commonly known simply as Donegal - is the fourth planet in the system and has a single moon named Seth's Jewel. A major industrial and commercial world, Donegal is home to numerous major and minor industrial and business concerns. And has been a national or regional capital world since at least as early as the early twenty-fourth century.[1] Orbiting above Donegal during the thirty-first century were two space settlements known as "The Tin Cans", which were as well developed as the planet below.[1]

Planetary History[edit]


In 2301 Seth Marsden arrived on Donegal, having recently departed the world of Skye. Marsden had been the most trusted advisor to Ian McQuiston, the owner of the vast Skye Traders conglomerate and ruler of the Federation of Skye; whatever the reasons for their quarrel - some believed that Marsden had deliberately initiated the argument, to give himself a pretext to leave - Marsden planned on establishing his own realm in a fashion similar to that of his former employer. Beginning with the Donegal Freights and Goods company, Marsden took Donegal - a generally pleasant world with abundant resources and an amiable climate - and followed in McQuiston's footsteps;[6] by 2314[5] Marsden had brought Donegal enough influence in the region that it became the capital of a new state, the Protectorate of Donegal.[6]

Apocryphal Content Starts

The information after this notice comes from apocryphal sources; the canonicity of such information is uncertain.
Please view the reference page for information regarding their canonicity.

The database of the (apocryphal) 1989 video game MechWarrior, set around the year 3025, gives a population of 3,651 million for Donegal and describes the environment as "tropical" (out of only three broad impressions of planetary environments given in the game, these being "desert", "ice", or "tropical"). The description one-liner reads "Rich in diamonds, rare metals, and traders."

The Jihad[edit]

The Word of Blake launched a raid on Donegal between the 14th and 17th of March 3068, while also launching raids on Coventry and Hesperus II; the three raids all featured support from Blakist WarShips or Pocket WarShips.[8] The Word of Blake then took advantage of the reduced defenses on Donegal to launch a full assault on the 27th of February 3070, attempting to occupy the world in a fashion similar to that already used against Hesperus II.[9][10] Donegal would be blockaded for more than a year; on the 14th of February 3072 a coalition of forces from ComStar, Clan Wolf-in-Exile and the Lyran Alliance Armed Forces all under the command of Precentor Martial Victor Steiner-Davion successfully broke the blockade and liberated Donegal.[11][12]

The Blakist attack on Donegal saw the planet showered with tactical nuclear weapons which targeted not just defense centers but also educational and business facilities, and the Lockheed/CBM plant located on Donegal failed to survive the Jihad.[2]

In December 3076 it was speculated by the media that Donegal was the site of planning or troop movements in support of an anticipated invasion of the Word of Blake Protectorate due to a combination of factors, which included the arrival of the Monarch-class Dropship Little Big Horn, believed to be the command vessel of General Belle Lee of the allied coalition. The Little Big Horn arrived with almost no notice at a cargo port near Wytheville operated by General Dynamics on the 2nd of December; the Wytheville port which was then promptly placed under a security lockdown for all traffic other than allied coalition forces. All civilian traffic was routed to the Meridian drop facility, roughly a thousand kilometers away, while at least three secure convoys landed at Wytheville in the next 24 hours.[13]

Adding credence to the media speculation was the arrival of the security detachment associated with Duke Robert Kelswa-Steiner; it was rumoured that the other two private convoys to land at Wytheville were bringing Field Marshal Katherine Sandoval-Ito and Tai-shu Isoroku Kurita and their attached entourages to Wytheville from Bladensburg, where both parties had been staying in seclusion for several weeks. While this wasn't confirmed, the planetary Civilian Space Transit department did confirm that at the time, there were more than 70 assorted vessels present at the local zenith jump point, with several other DropShips inbound.[13]

  • Chekswa School of Literature: One of the Lyran Commonwealth's biggest fine arts schools, located near Media City. Graduates include some of the most prominent journalists and screenwriters in the Commonwealth.[60]
  • Doons School of Business on Donegal: The pinnacle of Lyran corporate education programs, located in East Marsdenville. Emphasizes every area and facet of business and economics, and offers its best students internships with local businesses.[61]
  • East Marsdenville: location of Doons School of Business.[61]
  • Marsdenville: Planetary capital city prior to the Jihad, located on Lockenar.[2]
  • Martial College of Donegal: The Martial College of Donegal was the oldest academy in Lyran space, but as of 2765 its facilities were looking increasingly outdated. Despite this, its status as one of the few Lyran academies with programs geared towards WarShips and black navy crews kept it operational all the same.[62]
  • Ohav Shalom: Largest rabbinical institute in the Lyran Commonwealth, consisting of a synagogue and teaching facilities. Located in the Piety Range on the Hinterlands continent.[63]
  • University of Washington on Donegal: One of five major non-military research universities in the Lyran Commonwealth, specializing in computer technology and communications. Equipped with some of the Inner Sphere's best computer science facilities, outside of ComStar and the Word of Blake. Located in the Queen Anne Hills on the continent of Seattle.[64]
  • Wytheville: location of a DropPort.[13]
