Phantomlope backstory

At night Celestia and Luna hear a filly’s cries so they walk towards the entrance of the castle and open the gates.

What they see is a basket with a filly inside. Celestia and Luna, we’re confused about how this filly ended up here. Celestia adopted the filly and named him phantomlope.

13 years later
Phantomlope became a royal guard and begin to have feelings for Luna the princess of the night.as a stallion he feels ashamed that he is not a alicorn but he thinks maybe he will become a alicorn so he went to talk to celestia.

“Is it possible to become a alicorn” said phantomlope with a big smile.”maybe it is possible”celestia said while drinking tea.”why”said celestia,“because I am thinking of becoming a alicorn”said phantomlope with a smile on his face.

“Your training of becoming a alicorn starts tomorrow” said celestia while she winks at phantomlope and smile.“Tomorrow it is” phantomlope said.
