Fact that Claudius took the power in 41 CE meant that his freedmen and advisors, Narcissus, Callistus and Pallas, would be involved in ruling in Rome. They were slaves who shared power in such a way that they did no get in the way each other. Narcissus in particular had enormous support from emperor and had a really big influence on his decisions. He often acted on his behalf and represented him.
