The Alicorn Princesses [[Princess Celestia|Celestia]] and [[Princess Luna|Luna]] were the legendary rulers of [[Equestria]] during the [[Golden Age]]. (Mythology describes a variable number of alicorn princesses, leaving historians somewhat uncertain as to how many exactly there were in the Golden Age, but the historicity of Celestia and Luna is above serious question.)

Legend and what limited firm information is available to modern scholars agree that the Princesses went missing during the Catastrophe, possibly in a battle with a giant draconic deity from beyond [[Equus]]. Separating historical fact from myth and embellishment is not readily possible.
