Thanks to Seattle's Angels for their review of Quantum Vault!

Fleeing from a shattered future that never should have been, a mint-coated mare galloped into the Quantum Vault Accelerator...and vanished.

She awoke to find herself trapped in the ebb and flow of realities, facing mirror images that were not her own; and driven by those she had wronged to change history for the better. Her only guide on this journey is Hal, a pegasus from her own spacetime, who appears in the form of a hologram that only she can see and hear.

And so the minty mare finds herself vaulting from life to life, striving to put right what once went wrong, and hoping each time that her next vault, will be the vault home...

(CROSSOVER NOTE: Savvy Ponies may have noticed that Quantum Vault is not ~exactly~ the same concept as Quantum Leap. It's meant to be more of an homage, though I've listed it as a 'crossover' due to the considerable, intentional similarities between the two. I wanted to have some freedom to put some original elements in the tale, and to keep things interesting, so readers can't just assume what will happen next based upon knowledge of Quantum Leap. I hope it's working out for everypony!)
