Arthur Manchester is Tom Mason's mentor and former professor at Boston College, where he was Chair of the History Department. After the invasion, he helped found the Charleston community and government and was elected Majority Leader. However, his overcautious attitude and his desire to keep Charleston hidden until they could consolidate was seen as reckless by Tom and Weaver who believed that, with the Skitter rebellion, they had a real chance to fight back effectively against the Overlords. He had the whole 2nd Mass arrested when they attempted to meet with the rebels. However, General Bressler, the head of the Charleston military, disbanded the civilian government and arrested Manchester.
He was later released and the civilian government restored on the condition that he resign as Majority Leader, an offer with which he complied.
