Matthaios was a male Human serving as a Judge in the Order of Judges of the Eriaduan Empire. Matthaios led the hardliner faction that opposed Antonio de Borgia’s unwillingness to use the Eriaduan Fleet to seize control of the entire Galaxy instead of just the Outer Rim Territories. Despite that, he was met with opposition from Chief Justice Peitros who was a supporter of Borgia’s policies. Matthaios, being an ambitious man, had his sights set on becoming the new chief justice which meant eliminating Peitros in the process.
