Setrákus Ra is the political and military leader of the Mogadorians. It is also hinted that he may be somewhat of a religious figure. It is mentioned by Adamus Sutekh that the Mogadorians follow the teachings of Setrákus Ra, who they call their Beloved Leader, through a book of his creation; 'The Great Book'. He is mortal enemies with Pittacus Lore, who refers to him as his "counterpart and enemy". Despite this, Setrákus and Pittacus were once friends, many years ago when Setrákus was an untainted Loric. Pittacus is also the only person who can stand against and defeat Ra. It is common knowledge (to Reynolds at least), that both Ra and Pittacus are able to communicate with each other, hence the reason Eight believed himself to be Pittacus Lore's successor.
