There On The Battlefield She Stands

Is it just me or could this Twilight possibly be the one from king Sombra's timeline, maybe or so. I mean, we saw Dash from there, Rare's, P.P, Flutter's, A.J, and even Maud. So I'm curious about Twi. Though, my headcanon is Twi obviously failing her test for the School for Gifted Unicorns and then she starting to hate Celestia and then running away from Canterlot to find power and knowledge. As she travels she come to the north of Equestria, and it seems like she went there at a certain time cause it was the time the Crystal Empire and along with something else had returned. Twilight then quickly learns that the something else is a threat but the empire however was protected by a crystal blue shield. A evil plan then forms in her mind to get revenge on Equentria and her royal highness. She learns that though the huge shadow thing that she did not know of didn't have access to the empire she on the other hoof did. Twilight understood that in order to get revenge on Equestria she couldn't do it alone, she needed a weapon.

This all i've got for now cause i'm getting tired of the constant writing but ya u get the point.
