This was a timeline where the Saxon Master invaded Earth with the Toclafane in 2008, decimating humanity.

In this timeline, they Pyroviles prevented the Eruption of Mount Vesuvius, which was a fixed point in time, by draining the volcano's power to power their converter in order to turn humans into Pyroviles.
