I looked through the L5R wiki and, eliminating all vassal families formed after 1110, here is the list of vassal families that I think exist within the setting-- assuming everything carries over. Have I missed any or are there any on this list that I should have removed but missed?
I think it would be nice to be able to give stats to all the vassal families to greatly expand the player options. If anyone wants to get started on their favorite clan as we sort out the list, it would be a good start.
