The Star Brotherhood

by Thomas DePrima

2013

Undercover intelligence agent Trader Vyx leads a small team to Bleadalto, a violent world where slavery and organized crime exploded after a fallen regime. Their quiet fact-finding assignment turns into open conflict when they cross the Star Brotherhood, a syndicate that does not tolerate interference.

Series background & context

AGU: Space Command Intelligence follows the undercover side of the Galaxy Unknown universe. Instead of captains on bridges, these books track Trader Vyx and his small team of covert operatives as they move through black markets, slaver dens, and criminal strongholds where a Space Command uniform would be a death sentence.

Vyx begins life in the universe as a solo field agent introduced in Trader Vyx, posing as a weapons dealer to trace stolen Space Command technology. By the time of The Star Brotherhood, he is leading a tight-knit cell of intelligence specialists and former slaves who owe their freedom to one another and to the missions they take.

The first AGU: SCI novel drops the team onto the planet Bleadalto, a chaotic world where slavery, counterfeit currency, and drug syndicates have filled the power vacuum left by a fallen regime. Their official assignment is to gather information on the situation and map the scope of the slave trade. In practice, they are walking into a quiet war between rival Brotherhood factions that quickly becomes lethal.

Space Command Intelligence work is more about patience and improvisation than straight firefights. Cover identities have to be built and maintained, relationships with informants must be managed, and every barroom conversation or dockside deal can tip the balance between staying invisible and ending up on a crime lord's hit list.

Because Vyx and his people operate between official borders, their stories reveal how much of the galaxy's real business happens far from capital cities and fleet bases. Operations link back to the main A Galaxy Unknown timeline, but focus on the intelligence groundwork that makes the big victories possible, from tracking slavers to undermining hostile powers before fleets ever arrive.

If you like the Galaxy Unknown setting but want a slightly grittier, more street-level view, the AGU: Space Command Intelligence books fill that niche. Expect smaller teams, tighter missions, and plenty of scenes where the most dangerous weapon in the room is simple information.
