BATS! bad ending

Dear Princess Celestia,
    Been hiding under apple basket for three days. Ponyville is lost. There may still be hope for the rest of Equestria, but only if we act fast. There is only one option available- the Elements. Buck the tree of harmony, chop it down if you have to, just get the Elements, get Luna and meet me at the Sweet Apple Acres barn at noon, while they sleep. If I'm not there consider me turned. Included with this letter is a failsafe spell I've devised which will kill me remotely- use this IMMEDIATELY if I don't show up. They already have Discord, an Alicorn would make them unstoppable. If I am unable to meet you, I shall activate the spell myself at the designated time. The prospect of me becoming one of them is far too dangerous. If all goes well, we may still have a chance. Equestria might survive. I only pray to Faust that it works.
    Your faithful student co-princess,
    Twilig-

Dearest Sister, Twilight's missive sounds most dire! Should we render assistance?
I'm sure she's fine.
