What I don't understand is, if the Manifest Path are interested in the Zuma, why they don't devote some time to getting information about them? They can get plenty of information (of questionable quality, of course) through the Dwilight University, Libidizedd Trading Company, or Dwilight Trade Company, or other guilds and religions. I know that these may not be the 'proper' channels for information about the Zuma, but Gornak and many others close to the Zuma or who have had contact with the Zuma would be happy to share what they know.
If nothing else, these would be good avenues to find out what you need to find out, so that you at least know what you don't know about the Zuma.
