Born in a relatively unknown world in the Colonial Regions, Mephilius' family was made up of natives and colonials, creating a vague humanoid species upon further intertwining. While the story of his youth is unknown to the current Galactic public, he is well regarded as a clever tactician and a dangerous craftsmith of words and politics. From his youth and flirtations with a young Jedi, to his ultimate climb on the ladder of power in the New Republic, to the rising GE, Mephilius was greatly credited with the successes in anything which involved him, though some say he was simply able to turn situations to favor him. In the New Republic, he'd become regarded as one of the best commanders, having learned under the Republic's naval genius, Admiral Akbar.
