Foreshadow

Foreshadow is an earth pony NPC who can be found in front of the Hermit's Cottage in the Heartlands atop a hill at the intersection of the paths to Ponydale, Midway Village, and the Ferry Launch. Talking to her gives players the option to start the Shown Their Work quest.

Trivia

Foreshadowing is a literary device in which a writer gives an advance hint of what is to come later in the story, and helps the reader develop expectations about the coming events in a story.
During Open Server Event 9 of August, 2015, she had an empty merchant menu that allowed her to buy items from the player but had nothing to sell. This was a coding error and was corrected shortly after the Event ended.
