Similar to Twilight, Moondancer, one of her old friends, is also an astute for knowledge, and gifted the Cutie-Mark that can be related to a mastery over Magic. Uniquely, her Cutie-Mark also represents a Moon, which is further enforced by her personal preference for sleeping during the Day, and studying throughout the Night. It is my recommendation that she be treated as a Primary Candidate, thanks to these conditions, and her close proximity, currently residing in Canterlot, to become Princess Luna's first Student. I believe there is much unique to the Night to be imparted, and the two could explore such together. An invitation is currently written up, and waiting for signed approval.
