14:03:56 2nd April 1893: H.G. Wells accelerated his time machine to -8.8Ms/s and slid into the past. 11:35:42 9th October 1881: Hoping to send wireless power through spacetime¹, a young Nikola Tesla powered up her Chronos Power Coil to 1.5Tev. The surge of energy hit the time machine as it passed through that second, sending a feedback loop resonating across the fabric of the universe. Compression. Eternity in an instant. The universe in a pinhead. The resulting explosion² thrust Nikola through time sideways, into a different reality.
The reality for Nikola however, was that she'd never stay in any given universe for long. Eventually the ripples of The Event would find her and push her somewhere, somewhen or somewhow³ else. If she could just stay in one place long enough perhaps she could find the technology to stay there, or even make her way home.
¹Einstein and Tesla had discussed the idea of spacetime at length, but it was some years before Einstein could develop a robust mathematical proof for peer review.
²If you could call the cleaving of the universe an explosion.
³That is, across the fabric of probability.
