Likewise House Wallach looks interesting and fine to me, too. So: is this the sum of the various categories that players will be able to belong to? - Fremen (excluding Sietch Tabr). - Bene Gesserit (agents only) - IX (agents only) - Tleilaxu (agents only) - House Corrino/The Emperor's agents (specifically no Sardaukar). - House Harkonnen head of house and agents - House Wallach head of house and agents - Spacing Guild (agents only, no navigators) - CHOAM (agents only) - Various Houses Minor head and agents (whether the Minor House exists under Harkonnen, Wallach, or another major house except Atreides and Corrino) Is that the full list? EDIT: On reviewing the list I'm more convinced there's any number of reasons that could be used to shoehorn agents of these factions onto Dune. It is, after all, one of the most important places in the known universe and one could easily come up with reasons for agents of any of these groups being present on Arrakis. Even the Houses Minor can be sent in by a House Major with that intent. One more reason for single-thread creation focused on Dune to start with, I think. What do other minds reckon?
