During the second world war the League confronted a Russian mage/scientist who was working for Hitler in a top secret research facility. The Scientists at the facility where supposed to be working on top end anti gravity effects, however the scientist was usurping the facilities power and technology for his own nefarious ends.
The league broke in and sabotaged the facility supposedly destroying it, as the members of the league escaped and during the resulting explosion something occurred to effect the mages.
From then on the group had problems gathering and keeping hold of quintessence, effects that before had seemed easy would falter and fail more often than would be expected. While not crippling it was somewhat difficult to work with and several quest where carried out searching for a solution.
During the Cold War it appeared that the scientist had gone renegade from his technocratic masters and was working for the soviet government research into
The league raided the research facility. During the assault on his compound the League destroyed what they understood to be Rasputin’s doomsday device, in its final moment the backlash from the device scoured all but a fraction of the League’s Avatars from them, leaving them weakened.
The Scientist, codenamed Rasputin by the League for his extreme resilience, escaped again and for the past three decades the League have tried to survive an increasingly hostile world and seek out Rasputin to try and reclaim their Avatars.
In the past few months the League has hit a break, while cleaning up some business for the London Mage Council they happened upon a lead to one of Rasputin’s assistants working with the Technocracy, they tracked him down in transit during an overnight stop at an abandoned Soviet shunting yard in Belarus.
