Lorien. The Mogadorians The Mogadorians or Mogs are the main antagonists of the series. Mogadorians are aliens from the planet of Mogadore. They set out to conquer Lorien because their planet is dying from a lack of resources. The Mogs follow the teachings of Setrakus Ra through his Great Book, which commands violence and respect for the strong. They often say "By Ra" concerning their leader. The planet Mogadore is twice the size of Lorien and around a fifth of Earth's size. They hunt the Garde out of fear. They plan on conquering the Earth after destroying the Garde. In the meantime, the Mogs gain power in the United States government. The Mogadorian soldiers and scouts have pale white skin, black eyes, and serrated teeth. They are vat-born clones made by Setrakus Ra and his scientists. They are stronger and faster but not smarter than Trueborn Mogs. Trueborn Mogadorians are identical in appearance to humans. They are gregarious and like cities and crowded places. The Mogadorians have difficulties conceiving children; if a child is born, the mothers often die in childbirth. Setrákus Ra Setrákus Ra is a Lorien who becomes the leader of The Mogadorians. He arrives on Earth at the end of The Power of Six. Ra is tall but becomes tall when using his growth Legacy. He is tanned with short hair and a chiseled jaw. There is a "purplish scar" around his throat, given to him by Pittacus Lore. Because Setrákus Ra had been his best friend, Pittacus banished him from Lorien instead of going through with the scheduled execution. Ra is the author of the Great Book, which the Mogs follow faithfully. It is about war and how to conquer and consume everything in their path. During Six's fight with him, she noticed Ra had unique scars around his ankles, possibly hinting that Ra may be one of the original Ten Elders. In that fight, Ra uses his shapeshifting Legacy to mirror her features, which fools the Garde when they come to her rescue. In The Fall of Five, Ra reveals that Ten is his heir and comes from a prominent family connected to the Elders. This most likely means that Setrakus Ra is the tenth Elder who "died" in the Secret Wars. In The Revenge of Seven, Ra tells Ten that she is his granddaughter while aboard the Anubis, the Mog Flagship orbiting Earth. Later,
