Most legends are born from a single small grain of truth, others are born from the pure imagination of a few ponies, but as Ponyville very well knows not all legends are that. When something saves Apple Bloom from a pack of Timberwolves will she be able to convince the others of what she saw or will she just have to find the truth herself?

(Thanks to _Medicshy for giving me his feedback on this. Anything about the characters in the story that seems off is probably an instance of me not taking his advice.)

A direct sequel to At Home On The Range.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Big Macintosh is a stallion of few words, but that doesn't mean he's slow or uneducated. Unknown to any outside the Apple family, he's a wiz at math and finds himself smitten with the one pony who could share his love for numbers, and who just so happens to be the personal student of Princess Celestia; Twilight Sparkle. With a "gentle" nudge from his persistent sister, Big Mac manages a date with the purple unicorn, but a relationship might turn out to be more work than either one bargained for.

Granny Smith has been making Zap Apple Jam for decades but there's something about the savory treat she's not telling.
