The Cursed Angel

Long ago, when Equestria was starting to burst with life, Alicorns were the only living horse that existed. They frolicked all day and gazed at the stars at night. No Alicorn had to use their magic since a special kind of creatures did it for them… Angelic Alicorns. These Alicorns were given orders to grow fruit, make weather and bring the sun and the night sky by the creator. For 100 years, the land was fruitful, and the Alicorns lived in perfect harmony, until one day. An Angelic Alicorn believed that since he was given a big job and he could do it alone, he thought he could do more. He began to expand his use of power. However, when he did, sharp horn grew all over him and he believed he was more powerful than the creator. He began to corrupt the regular Alicorns and taught them to use powerful magic. Seven other Angel Alicorns; Generos, Kindnis, Loyas, Honestry, Luaghni, Magicnos and Sacrificous grew worried and so they decided to warn the Creator. The creator had foreseen what was taking place and told the Angel to go to the center of the land and there would be a tree that sparkled like a diamond. There they would make the Elements of Harmony. On their way to the center of Equestria, corrupt Alicorn armies attack the Angels. Being the most powerful one of the Angels, Sacrificous told the other to go and create the Elements while he stalled the army. By doing this, the elements were created but one was missing. The Element of Sacrifice. Sacrificous gave his life to the creation of the Elements of Harmony. Not all of him died though. The Creator turned his spirit and energy to a gem that only an Alicorn with an Angel's pure heart can use it. After the creation of the elements, The creator was mad on what the Alicorns did. He called down on his corrupted creations and told them that since they believed that they didn't need him or the Angels, he would give responsibility to the ponies to bear the land to grow, control the weather and raise the day and nights. He also made every Alicorn different, by removing their horns, wings or both. Each type was given a specific task to control. In one area, south of the land, laid a sanctuary to the creator and his forgotten Angel. From the power of the Creator, His son the Savior and The Sacred Spirit, The Sanctuary was kept hidden and would remain pure from the world, so long as the ponies would remain loyal. As for the Dark Angel. He was banished to the center of the sun. However, every 3000 years, his power builds up and he moves both the Moon and the Sun and binds them into one, which allows his creations and his corruptible temptations seep to the land to rein terror. A prophecy foretells that the last eclipse will have a red moon and a blue sun and he will rise to reap the land, unless a wielder of the element of sacrifice can stop him.
