Battletech.
Early on, after the collapse of the Star League and in the early stages of the First War of succession, the head of the interstellar communication corporation comStar (a fellow by the name of Blake) realised where things were headed. In order to preserve interstellar communications via the FTL Hyperpulse Generator network, they transformed themselves from a Corporation, to a
Religion; they mysticised the operation of HPG stations, along with a lot of basic technical maintenance procedures.
And it worked. Perhaps too well, in fact, because centuries later - when the LEague was stabilising, and technology trends had reversed from a steady decline, back to actual GAINS, and ComStar tried to re-cult-ify itself?
The radical fundamentalist element within ComStar, who
believed the religious stuff, staged a coup/rebellion, calling themselves "the Word of Blake", and launched a jihad of retribution on the rest of mankind for being uppity heretics.
...
So.
Comstar, or Word of Blake?
