Noah was one of the two brothers in charge of Rylium. He was clearly the senior to his brother, Abel. Amongst other things, he was effectively the chief public relations officer for the company. In one well-attended event, he literally administered nanobots to a woman in order to cure her deafness right in front of a throng of onlookers.
Nevertheless, in private, he was fairly ruthless, even sending his brother to Merced Magnet School to fix the "Aisha problem" by, effectively, any means necessary.
