The Porthos system was home to at least one habitable world or construct and as at 3145 was located in the Periphery region known as The Barrens.[1][2]

System Description[edit]

The Porthos system is located near the Santander V and Thule systems.[1][2]

System History[edit]

The Porthos system was colonised by the faction known as the Inheritors,[3] and was either colonised during the Third Succession War or became significant enough during this era for Inner Sphere nations to begin recording it's location on maps.[4][5][6][7]

Political Affiliation[edit]

Planetary History[edit]

The Succession Wars[edit]

Porthos was originally settled by Inheritors from the Elysian Fields.[3]

Clan Invasion[edit]

The system was quickly conquered by Clan Ghost Bear during Operation REVIVAL in September 3049. When the Ghost Bears originally arrived they had expected no resistance, only to find a single warrior standing in their way: Uchi Tikidomo, formerly of the DCMS, who had retired to Porthos where he had planned to live out his days in peace after serving with distinction in the War of 3039. Tikimodo met the Ghost Bears at their landing site in his Archer and promptly challenged them for control of his defenseless world. The Ghost Bears immediately accepted his challenge, and Star Captain Ian DelVillar of Ourse Keshik's Alpha OmniMech Star won the right to face off in his Nova against Tikidomo. While the mismatched fight ended in a predictable fashion, Tikidomo's tenacity in the face of adversity so impressed the Star Captain that he agreed to hire the former warrior as a liaison between the planet's government and their new Clan overlords.[35]


The Bears had trouble integrating the system into their Occupation Zone, however, and more problems integrating it into the Ghost Bear Dominion. In the early 3090s, the Bears saw that Clan Hell's Horses was just giving up on some marginal systems, and decided to follow suit. Porthos was handed back to the Inheritors and the Bears withdrew to more complex systems. Porthos later joined with Santander V to form the proto-state known as The Havens.[3]
