Saxton Hale Doesn't Go To Ponyville

Saxton Hale doesn't go to Ponyville. I understand if that means you want nothing to do with this story. Soldier does though!

What happens when Saxton Hale is too busy to go to Ponyville and give you a story? What happens when a fight between ex-roommates leads to Soldier being trapped in a world of ponies? Will Ponyville survive? Will Twilight have an aneurism? What is a hypotenuse? All this (except that thing about Hypotenuses) inside!
