I gave Sunburst a bit role in one of my fanfiction stories (which was slowly published over the first half of this year on FIMFiction.Net), and actually got pretty close to the whole antiquities interest considering it was months before this episode was released and the episode preview giving no clues about it!



(Without giving too much away of the story, Sunburst - who is living in Canterlot during the time the story is set in, same as Season 1 and before the return of the Crystal Empire - was researching artifacts in "The Luna Vault", a museum of sorts that was made from the thousand years of accumulated birthday and Hearth's Warming presents Celestia left for Luna when Luna was in exile, when he gets caught up in the events of the story and KOed, only to be rescued and sent to a hospital to recover.)
