Among the most important technological advances of the Star League era was the Hyperpulse Generator, a variant of the technology of the Kearny-Fuchida Drive that allowed interstellar communications and made possible the smooth rule and operation of the massive Star League and Inner Sphere. With the prime circuit of the Star League Communications Network (SLCOMNET) located on the worlds of the Terran Hegemony, the HPG network suffered crippling damage during the Amaris Civil War. While the House Lords could agree on little after the conclusion of Amaris-Kerensky War, all knew that it was vital the HPG network be restored, with Nicoletta Calderon nominating Jerome Blake for the position of Minister of Communications of the Star League on October 10, 2780. As the highest-ranking member of the SLCOMNET hierarchy who was not captured or killed during the Amaris coup, Blake’s heroic efforts to maintain communications during the crisis earned him a reputation for integrity.
Blake recognised two great responsibilities in the wake of the collapse of the Star League: preserving as much of the currently available technological knowledge as possible, and preventing the Successor States from seizing the interstellar communications network and misusing it for their own destructive purposes. To this end he set about transforming the Department of Communications into a neutral trans-national corporation dedicated to the operation and preservation of the HPG network, renaming it ComStar.
In 2788, Blake took control of Terra and declared it a neutral world. He offered secure interstellar communication to all Successor States that would pledge to respect the neutrality of the HyperPulse generator stations and personnel. The Inner Sphere leaders recognized that open communications were crucial to their survival and agreed to Blake’s demands marking the beginning of the order of ComStar. Blake created the First Circuit to administer ComStar’s affairs and fostered a “secret brotherhood” mentality among ComStar’s members in order to keep the secrets of the Star League safe.
After Blake’s death in 2819, Conrad Toyama of Dieron took control of ComStar. He replaced its corporate structure with a rigid, religious hierarchy, and shrouded its activities in mystic rituals. Toyama declared himself Primus, the highest authority in ComStar, bequeathing that august title and its responsibilities to every leader of ComStar who followed him.
Mercenary Review Board (MRB)
The Mercenary Review Board is an independent supra-national organisation that serves as the Human Sphere-wide official registrar for all legal mercenary units. It functions as a mercenary guild, brokering and arbitrating mercenary contracts in the endless wars in the Inner Sphere and also in the Periphery. Apart from registering mercenaries and providing a ranking system to gauge performance and reliability, the MRB also serves as a court of arbitration in contract disputes for both employers and mercenaries. If a mercenary unit is not registered with the MRB then it is usually (but not always) considered to not be a legitimate mercenary unit, and therefore not subject to POW rights, among other drawbacks.
While operated by ComStar as the MRB, it was at the same time also a criminal extradition service, a prisoner exchange and ransoming service, and a banking house. Arbitration of contracts by ComStar’s Mercenary Review Board provided a valuable safeguard on both sides, as any unit failing to perform contracted services after taking an advance found itself unable to evade ComStar’s almost universal reach. ComStar informed other potential employers of a rogue unit’s actions, and had the power to threaten an Interdiction against any House employing such a unit. To ensure fair dealings on the part of employers as well as those they hired, the MRB provided for a panel of ComStar administrators to hear claims concerning breaches of faith and to judge the veracity of complaints. Upon reaching a verdict, the panel broadcasted its findings throughout the Inner Sphere. As the reputations of mercenary units and their employers have a bearing on subsequent negotiations involving other units or Houses, violating contractual terms offers little profit to any concerned.
