After getting warped to Equestria by Twilight (due to her being the Element of Magic), a certain boy wizard faces the great challenge of not only finding a way back, but teaching a very hard spell to someone who never used it before (The 2nd Wizarding War is over, but Harry's not going back to Hogwarts)

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.
