There once was a jealous earth pony. Usually happy she disliked two things. Pegasi and Unicorns. She disliked how they had their horns and their wings. She could bear seeing them every day. Alicorns she absolutely hated. This jealousy of the alicorns drove her to discover the potion. The potion she discovered had no name but was able to turn anypony into an alicorn. It required the sacrifice of two ponies that were not the race of the one who made it. She had no remorse when she killed two of her closest friends. She drank the potion immediately after she was done. Her caretakers found her on the floor. She wasn't breathing. They rushed her to the hospital where she was deemed dead. The doctors left her in the room to tell her caretakers. When they returned she was gone. The next morning an alicorn blasted her way to the princesses throne room, and challenged them. She was defeated and imprisoned. The alicorn princesses decided to undo what the potion had done. This process was extremely painful and was supposed to take 3 days. On the first day they took her horn away. On the second they took her wings. On the third day they were going to take her immortality but she was gone. All they found was a note. Saying she would return to take her revenge on them.
