The Fallen Star is a quest in Diablo III, which happens near the beginning of the game. The quest is initialised when the character comes in contact with the meteor, which turns out to be a man that has mysteriously fallen from sky. After the quest, it is revealed that the man was actually the Archangel of Justice, who removed his wings and become a mortal to save humanity. In this quest you will have to find the cause of the destruction and the living corpses. Once you find the cause, which is actually a man, you will help bring a sword and return it to the man to restore his memory.
