A convergence of characters on Earth in the year 2050 A.D. with one change to history. The first steam engine was made with materials alien to the planet. The new element, Sinium exponentially increased the power output to the point of what another time line might call fusion. The byproduct of improperly formed alloys caused the reproductive rate to exponentially increase the number of twins, triplets and on even to some countries reporting upward of 8 children birthed at a time. In 200 years this caused a new exploration in humanity’s history out of curiosity and out of need, to space.
