Luster Dawn has learned a lot about friendship since moving to Ponyville, so she's most surprised to be called in for a meeting with Supreme Ruler Twilight Sparkle one day. And it's not about friendship either.

As it turns out, the subject of Twilight's meeting turns to an interesting topic: Legacy. And she says it's very important that she and Luster Dawn share this talk now.

Luster will soon learn more about her mentor than she ever anticipated learning, and will also learn a thing or two about how one's legacy can be shaped and changed.
