The TwiJack project is a series of short fics attached to various episodes, detailing a relationship between Twilight Sparkle and Applejack behind the scenes. The stories take place sometime during or shortly after the indicated episode.

The concept is inspired by several of the previous projects:
The AppleDash Project (Part 1 and Part 2) by bookplayer
The TwiDash Project by bats and Subsolar Drift
The RariDash Project by Jake R

Note: The TwiJack Project does not take place alongside The RariDash Project. They are of two separate continuities.
