Lathan Devers (Foundation and Empire) is a Trader sent by the Foundation to spy on Bel Riose and determine his military intents. He and Ducem Barr steal a message sent by Brodrig to Riose, attempting to use it to make it seem like Riose is betraying the emperor. However, this proves both futile and unnecessary, since socio-politic forces work to prevent Riose from defeating the Foundation. In the next story, he is described as having died in the slave mines, presumably a political prisoner under the tyrannical rule of the first Mayor Indbur.
