Planeswalkers are mystical beings that can travel between universes. They have the power of near-infinite magic at their fingertips.
When Garruk, a human planeswalker, chases his prey Liliana into the land of Equestria, he starts a chain of events that will lead ultimately to a war with Equestria.
Twilight Sparkle, one of the four alicorn planeswalkers, must find a way to settle the conflict before her world is destroyed.

(A crossover with Magic: The Gathering. As such, it contains violence, spellcasting and ridiculous amounts of fun. Strewn about the story are links to relevant Magic cards. At the end of each chapter is a fanmade card related to the story so far.)

It's been a few months since you ended up in Equestria through magical (and irrelevant) means. You've been working on the Apple farm ever since, helping out Applejack and her family with the upcoming harvest. After a hard day of work, though, the mare decides that she wants you as an honorary member of her family.
