This was a poster for a my little pony fanfic of luna.
 
Story: When Luna was banished to the moon she was infuriated. She wanted revenge against Celestia so she used her magic and knowledge of the moons minerals that it held to make automaton versions of herself. They were programmed only obey orders from her with no emotion. However, they became more “pony-like” in a way. They shared jokes with each other and often had angry disputes as well. When her banishment was nearly over, she knew these automatons would do nothing to stop her from becoming a queen. She abandoned them for 5 long years and soon after they had made their move onto Canterlot. The royal guards tried to fend them off, But it was futile as they had guns to pick them off from a distance. Celestia had tried to rid them off of Canterlot, but she grew weak and was killed by them. The mane six tried too use their elements against them, but one was to scared of what they might do to them and betrayed the mane six, letting them die from their relentless assault. Now there are two queens and a princess. Luna was queen of Canterlot and aiding her was Twilight Sparkle queen of ponyville. Luna couldn’t control the sun, but Twilight had made a machine to control it remotely. In the end Luna may have became a queen, but at what cost? Her sister, close friends, and innocent royal guards were dead. No magic can bring a pony back from death. In the end she was left with her regrets.
