Normandy Heresy

The Normandy Heresy is the event that marked the Gershwin Company's creation from the remnants of the Old Chapter, and the start of Pierrepont Gershwin's control over said Company.

Background
Gershwin was an Aspirant in the Old Chapter, whose actual name and founding have been erased. He was being trained by the Chapter Master, Jaspair Whompus, when he violently killed a visiting Inquisitor by beating him to death with an unloaded gun, saying that the Emperor was not, in fact, a god. Whompus ordered him executed for heresy.

Gershwin was not killed immediately solely because Whompus had received new orders that the previously fleet-based Old Chapter was to take on Normandy as a home world. He decided to make an example out of Gershwin, by killing him in front of all Normandy, and his own men.
