Thanks for adding the Faction Creator to the Workshop tools. I tried making a new faction and after I got a city going I discovered that it has no tech tree. In the Research Technology screen there are just five white (blank) circles where normally there would be Civilization, Warfare, Magic, etc. I noticed that in the Faction Creator it does ask whether your race will be Kingdom or Empire so it should be able to assign it the Kingdom or Empire research tree based on that.
