Atlas was a legendary Titan, a son of Titan Iapetus. He was in a lot of stories, starting with the story of the exploits with the hero, Hercules. Atlas led a battle of Titans against Zeus which lasted for ten years. Eventually Atlas was singled out by Zeus and forced to hold up the heavens as a special punishment. The Earth goddess gave Juno, Jupiter's wife, a tree of golden apples as a wedding present.
Atlas's daughters had the role of protecting it. Hercules was ordered to fetch the golden apples from the Pleiades, Atlas' daughters, so he asked Atlas for help. Atlas had Hercules hold up the heavens while Atlas went to look for his daughters, who had the apples. Finally Atlas returned, but he didn't''t want to take over holding up the sky again. He had enjoyed his brief break and told Hercules that he would deliver the apples himself to the king. Hercules tricked Atlas into taking the load back by asking Atlas to hold it while he shifted the load.
The Sovereign Order of Monte Cristo knew the importance of Atlas and his role of holding the world and the sky upon his shoulders. And so to make sure that he stayed motivated and focus they gave him words of encouragement. One of the encouragement's was the promise of a book and a movie one day being made about him. This pleased Atlas greatly and stopped him from dropping the world.
