So:

-Characters not from Nickelodeon or the Fanonverse are special and united by some spiritual bond

-The spiritual bond is connected to this powerful wave of darkness

-The darkness, their "mothership" sucks them up

-The Curators clean up the meess by replacing similar characters with the spiritual bond

-People remember both timelines

-Life goes on
