Source Code, the pony from another planet... Planet Earth. He was once a game developer for a small indie game company that he and his friends made together. Now, a blue coated unicorn with a yellow mane, somehow finds his way into being tutored by Princess Celestia herself. He soon finds out about magic, and subsequently learns about how performing spells is grouped into three different groups. Rune Based Magic, as he soon discovers, is very close to his old hobby...
Coding.
Will Source Code make a name for himself? Will he live life out like he had on Earth in a dead end job? How is he coping about being forcefully ripped from his comfortable, though boring, life on Earth?
