The War of Titan

When I woke up I heard explosions and sword fighting.  I looked out my window and saw a darkened Twilight and Princess Luna fighting her.  I got my Five Seven the only gun I brought with me to Equestria and immediately teleported to Twilight to see what the commotion was about.  But as soon as I was in her sights she shot war spells at me.  I teleported to my flying Humvee.

As I got in the vehicle I wondered where I should go. As I got engine started I remembered a beautiful pond south of Ponyville and that's where I decided to go.  A few hours later Princess Luna, Applejack, Rarity, Pinkie Pie and, Fluttershy arrived.  They asked me who and why I was here I responded "I'm Comet Spark and I'm here because this was the safest place I could think of to go to." Luna said "Alright you can stay here then, but may ask you a few questions?" I answered "Yes." She asked me "If I have ever had a fight in my life?"  I responded "Yes, I have been in 2 wars though out my entire lifetime." Luna said "May I ask for help training the main six?" I replied "Of course."

"One more question though, which wars and how old are you?" I answered 35 years old and World War 3 and Afghanistan.  Luna paused, then said "Where are you from?  I answered "U.S.A, Earth." Luna then said "Were you a human when you first came to Equestria."  I answered "Yes Ma'm."
