Toran Darell II is the son of Toran and Bayta Darell and the father of Arkady Darell, and was known for his advances in electroencephalographic analysis. He was able to quit his job as he receives a stipend from the Foundation due to his mother's services in thwarting the Mule. The stipend is sufficient for a comfortable home in a pleasant suburb, and allows the presence of a servant named Poli to take care of him and his daughter. His abrupt resignation was due to fear that the Second Foundation might learn of his activities and adjust him.
