The Republic faces yet another Rebel threat.

However, they had one hope - 10 pony Jedi Masters had earned both the fear and respect of the Rebels, promising peace as long as they maintained vigil over the Republic.

It was not to last.

In a very sudden turn of events, the Jedi grandmaster Luna disappeared.

With her disappearance rose rumours of a new sith lord, Darth Nightmare, inciting a new rebellion.

It wasn't long before the remaining 9 pony Jedi Masters, Masters Twilight Sparkle, Rainbow Dash, Applejack, Rarity, Pinkie Pie, Fluttershy, Lyra, Bon Bon and Celestia were similarly suspected of turning to the dark side.

One by one they disappeared mysteriously, all save Celestia.

In desperation the Republic turned to the proposals of the galactic corporation Blueblood Shipyards to make use of the planet Equus, homeworld of the pony jedi masters. The planet is a force nexus so powerful it distorts the very fabrics of reality around it, generating a gravity well powerful enough to maintain a sun in orbit around it.

Harnessing this gravity well they would be able to build a hyperspace cannon capable of annihilating entire star systems.

With this they hoped to create a deterrent to stop the Rebel threat for good.

Now the last Jedi Master standing in opposition to this plan, Celestia, has been accused of treason against the Republic and the Jedi Order and faces execution on the planet Coruscant.

However, the execution is interrupted by the arrival of a lone figure wearing the colours of dark side, wielding crimson sabers, the mark of the Sith.

Who is this Darth Twilight, and what is she after?
