Agents of the Vanus Clade are known as infocytes and also made use of predictive engines in order to base their calculations on all available data as well as prognostic simulations in order to determine the success rate of the operations. The infocytes are essentially human computing engines that are far different from mindless automata such as servitors as their skills were unparalleled in matters of strategy and tactics.
