The whole thing is based on Mage: The Ascension's traditions.
The Mages in the game are basically reality warpers who only think their power works based on certain magical traditions. The Sons of Ether work magic via machines and SCIENCE!, and they can't do much without something to build or wield. The Verbena, however, can only work magic using certain paganistic rituals and invocations.
The Technocracy is a group of mages who decided to establish science as the dominant way reality works. They mostly use high tech stuff. The Sons of Ether and Virtual Adepts defected from the Technocracy after the Technocracy decided to implement scientific break-throughs they didn't agree with. The disproving of Luminous Ether and the murder of Alan Turing, primarily.
I got the Cult of Ecstasy and Akaschic Brotherhood as the foremost. That's basically I SEE THROUGH TIME WITH THE POWER OF SEX, DRUGS AND ROCK 'N ROLL and MAGIC KUNG-FU, respectively.
“She'd become a governess. It was one of the few jobs a known lady could do. And she'd taken to it well. She'd sworn that if she did indeed ever find herself dancing on rooftops with chimney sweeps she'd beat herself to death with her own umbrella.”
