Centered on their namesake - the barren, choking, terrestrial planet of Blackrock, the Blackrock Interstellar Authority governs several small systems centered on the Gneiss system. By using arms and technology supplied by Blackrock Drive Yards, they sustain their status as a relatively powerful, but small pseudo-federation in the Sector.
Largely isolationist, the Blackrock IA is the militarized, political, outward-interested half, and exists so the BRDY corporation itself can pursue its goal of leaving the Sector by engineering a new type of dimensional technology - in effect, succeeding the Domain jump gate system, and reconnecting with Humanity at large. To aid them in this goal, the disaster-filled history of Gneiss has left them sitting on a hoard of jealously guarded exotic technology, and a whole ecosystem of space-borne, non-organic, hostile life to keep in check. The main exports of Gneiss are arms tech, orbital solutions, spaceships and medical supplies, unscrupulously handed to whoever can afford it, provided it does not threaten the corporation's interests.
Quality of life in Blackrock-controlled space can't be said to be much higher than in the rest of the Sector, but there are some professions you won't see anywhere else. Internal stability and societal mobility is quite high, and medical technology is advanced compared to most other places in the Sector. Officially, the Blackrock Drive Yards corporation is apolitical and works to emancipate the Sector, and the Interstellar Authority works to keep Gneiss safe from the unpredictable stragglers left over from the Domain. In reality, though, Blackrock's elites only have one agenda, and that is to leave the spent husk of the Sector behind. Knowing just how much is out there, left to discover, and with a tiny minority of nonhuman citizens reminding them of this fact, they are desperate to escape.
Blackrock-related minor factions:
Solace State, Lodestone Dimensional Technologies
Relationships with other factions (core):
Spoiler
Hegemony: Hostile
The Hegemony carries out a cold war with Blackrock, who they view as a major destabilizing element. Each faction has been pushing and pulling at suspectible elements in the Sector in order to weaken or influence the other part. Blackrock knows the Hegemony could wipe them out if they truly risked losing their absolute power over the Sector in the process, and The Hegemony knows they cannot risk an all-out offensive against Gneiss. Locked in an uncomfortable stalemate, Blackrock will weaken the Hegemony however it can, in order to buy breathing room.
Tri-Tachyon: Hostile
The Tri-Tachyons are always breathing down the neck of Blackrock Drive Yards, having attempted to infiltrate the corporation since the day it transformed from a drive system manufacturer on a backwater world into the most powerful arms manufacturer in the Sector. Blackrock IA's end goal is to decisively crush the Tri-Tachyon Corporation and supplant them as the guardians of Domain high technology. Tri-Tachyon execs would like nothing more than to crush Blackrock and seize their assets. Since neither scenario is likely to happen, a skirmish war is the end result... for now.
Sindrian Diktat: Suspicious
Unlike many minor military governments, the Diktat rarely trades with Blackrock Drive Yards, because their Hegemony-loyal past and connections makes them wary of incurring sanctions.
Independent worlds: neutral
Blackrock exports make them a household name among many independent worlds. Fear of being annexed by the IA, or of Hegemony sanctions, causes some systems to entirely shy away from involving themselves.
Pirates: Hostile
Blackrock will fuel anarchy if it benefits the corporation, but they also value internal order too much to let crime go unpunished.
Church/Knights of Ludd: Hostile
To Blackrock, the Luddites are diametrically opposed in ideology and outlook. Since they cannot be ignored, they must be destroyed, and the ultimate fate of the Sector is of little concern to Blackrock.
