Cheliax
Source: Advanced Class Origins, p. 15
Investigators can be found anywhere information is valued, and the politics of Cheliax play to their strengths. Investigators serve on both sides of the law in Cheliax, whether that means among the ranks of the dottari, the guards and wardens of Westcrown, or in the pay of shadowy groups like the Apsis Consortium or the Council of Thieves. The Thrune government also relies on investigators to ferret out dangerous traitors, while even ordinary nobles may hire them to uncover new and devastating gossip about their rivals.
