This story follows Dusk Shine and Luna from the F.C.E. & tells the story of how they came into being the way they are in the present. The story starts a little over 40 years before the events Emerald Spider: First Contact Equstria.
The Emerald Spider has been a member of the Amazing Sector Defense Force for nearly two decades, but his most recent assignment to stop an inter-universal criminal may just take him to one universe he didn't even think was a possibility.
There are constants and variables throughout any multiverse or timeline. Sometimes changing one or a few things can have huge effects. This is an alternate take on the end of PenStrokePony's "Past Sins", and beyond.
What if Celestia felt she had to use the forbidden powers Sombra used and Luna once used to protect Equestria? It doesn't matter who it was that caused her to go this far, this is the story of what happened after she succumbed to that power.
