Commander Maximinus Thrax was a Romulan in command of the ChR Decius in the 23rd century. In 2269, Proconsul Servius Tullis assigned Thrax the duty of claiming Arachnae for the Romulan Star Empire. Maximinus was quite old by this time, and believed it to be a suicide mission. This theory was further supported by the fact that most of his family was on board the ChR Decius for this mission. His son, Licinius, served as his first officer. (TOS novel: Vulcan!)
