Given that we're setting up worlds for Infinate Worlds, a setting were interdimensional travel to different happentracks is the norm, why not a world were someone is working to change history and has the power to do it?

Picture a Cabal mage who has over time, and without his doing anything to achieve it, has lost his contacts in the Cabal and is presumed lost and dead. He enjoys the freedom and goes off to fulfil a dream. This man comes from a late 21st century were the USA is a broken and dispised nation. He wants to go to a world were he can shape America's identity and have that America achieve what he sees as America's true destiny.

When the I-Cops find this parrallel they find a world where US tanks in WWII were FAR BETTER than the German ones and Paris was taken by the Allies on June 30th 1944 and Berlin fell to the Yanks on Dec 1st of the same year. Were the Allies were flying American jets (which seems suspiciously like Migs) in 1943! Were America launched the first artificial satilite in 1947! And satillite comunications are becoming the norm in 1952.

The I-Cops notice that large numbers of key American conservatives, including figures that won't be important for decades seem to have died either in accidents or sudden illnesses. And Jim Crow is being dismantled in the early 1950's.

They know someone or something that likes technology (and has brought the world almost to TL8) and hates right-wing politics (having moved America in a social democratic direction) is active here, how do they figure out what that is?
