Twilight learnd something about her home that she wish wasn't true.

She wan't the first to ascend to being an Arc Angel, but what happened to the last?

This is her path as she discovers, the darkest secrets, conspiracy, the death of thousands, and the truth of Celestia and Luna.

This is ten years after Twilight gets her wings. Best guess she would be 28 (I don't know how old she is now.) They're humans but with runs depicting what they are, Earthen, Angelo, Mage, or Arc Angle.
