Overview
Little about the Lord Commander's origin, expect that he was once known as Jack, as well was a member of the Infinity Guard and friend to John Goodspeed for 29 years. Until during an anti-matter energy blast that collated with the ship, Jack somehow gained dark powers by Invictus which corrupted him with terrible evil as he than overcame an insane path. Once reborn, Jack who by then called himself the Lord Commander soon build to build an army of his own and plan opening Final Space, a dimension where alien giants known as Titans roamed but he also became rather ill and is now currently dying, therefore the only way to save himself is capturing a mortal dimensional creature named Mooncake and the Lord Commander vows to stop at nothing to do so.
