Planetary InfoEdit

According to the (apocryphal) novel Wahnsinn und Methode, the planet of Icar (as of 2598) had 75% of its surface covered by water and had two continents with environments spanning the range from jungles to deserts to tundra, ideal for combat training purposes. Two mountain ranges are mentioned: The Dominarius mountains, featuring a high plateau, and the much smaller and lower Bellisardes which form a roughly equal-sided triangle. Icar's Capital city is Athena Magna.

Planetary HistoryEdit

Pre Star LeagueEdit

Icar was one of seven worlds settled by colonists from the Rim Worlds Republic between 2334 and 2338 as an attempt by Maxwell Rowe to create a buffer zone between the Republic, the Draconis Combine and the Tamar Pact.[1]

Star League EraEdit

Icar was a part of the Apollo Province of the Rim Worlds Republic and was conquered by the Lyran Commonwealth during the 2773-2775 Republic-Commonwealth War.[12]

Succession WarsEdit

Third Succession WarEdit

Icar was one of the diversionary raids launched by the DCMS in 2866 in order to divert Lyran forces from the Federation of Skye. [18]

Clan InvasionEdit

Icar was conquered by Clan Wolf during Operation Revival in March 3050, invading the planet with Supernova First and Second along with Alpha Assault Star of the 4th Wolf Guards. They were opposed by the 3rd Regiment of the 12th Star Guards, commanded by Colonel Hanna Caitlin, backed up by the 3rd Icar Armored Brigade. The initial Wolf assault was swift, quickly overrunning the Star Guards' 2nd Battalion just minutes after securing their landing zones, and when Colonel Caitlin attempted to counter-attack at Pofadder's Gully her advance was repulsed. The Star Guards attempted to retreat off-world but were stopped when Elementals boarded their DropShips at Cuanger and forced their surrender.[43]


Icar would be be conquered again during the Jihad when Clan Hell's Horses launched a invasion of the Clan Wolf holdings in the Inner Sphere in early 3071, acquiring holdings for their own relocation to Spheroid space. The first wave of attacks captured four worlds; the second wave captured another four, of which Icar was one. The first wave was launched between the 21st and 28th of February 3071, with the second wave falling somewhere between the end of the first wave and the 7th of April.[34]

Dark AgeEdit

In 3122, the Sarkon's Bloody-Handed pirate group raided three cities and took several thousand civilians as slaves as well as large amounts of precious metals and gems before fleeing. The Eighty-fifth BattleMech Cluster from Clan Hell's Horses Kappa Galaxy responded to the raid and pursued the escaping pirates.[44]
