Marsclock as you guys should realize is a Clone Veteran from the Clone Wars, who Palpatine discovered was Force Sensitive. During the war, Palpatine twisted Marsclock into darkness, preparing for Order 66 because Marsclock's inhibitor chip was damaged during the Clone Wars. After the Clone Wars, Marsclock became a Secret Assassin for Palpatine, and was also used by important individuals such as Thrawn and Tarkin. Even after the Clones began being kicked out in 18 BBY, Marsclock was kept because of his abilities in the force. But starting in 7 BBY, Marsclock was beginning to not be used for much anymore. It was because Clones had accelerated growth. By 7 BBY, Marsclock was 50 years old developmentally. He was however, not completely thrown out, as he was still used by the Empire even as late as 5 ABY. By this point in time, Marsclock was 74 years old developmentally. Marsclock fled with 13,000 Stormtroopers to a remote World far beyond the reaches of the New Republic in the Unknown Regions. Marsclock conquered this world, and began to expand his Stormtrooper Armada. By the time of 9 ABY, only after 4 years, Marsclock had assembled an Armada of 65,000 men. After this, he found Thrawn, gave him his Armada and loyalty. As of now, he is developmentally 82, but he is still doing pretty well, as Force Sensitive people can live longer than the Average Person (As the Average Jedi could live up to 130 years.) What is his Midichlorian count since he has managed to defeat even Grimblade in a fight. Grimblade was Force sensitive, though he had only an M Count per cell of 7,000 the bare minimum needed if he wanted to become a Jedi. Marsclock is a different story. He is more force sensitive than Grimblade, and while certainly not like Darth Vader/Anakin who has a M count per cell of 27,000 he has a sizable amount of Midichlorians, more than the 10,000 M Count per cell of the Average Jedi. Marsclock has an M Count per cell of 14,900 which means he has a higher M Count than even Darth Maul, but lower than those of Dooku, Obi Wan, Palpatine, Luke, Plageius, Vader, Yoda, Revan, and a few others.
