One of the most important characters in Galaxies at Wars. Harrison (or Harry as John and Luna call him so), is a extremely loyal man. He's the right hand man from John and Luna. He was a soldier from the UPE army forces but then left the army, because he hated how corrupt the army and the goverment of his country was. He traveled the world, where he once met John and Luna, who traveled with a group of rebels, Sebastian included. He and Sebastian soon became the most important members of the rebels.
