Looks nice! For the purpose of character creation, are there any guidelines as to what would fit to the campaign? From the looks of it, the Beta is somewhat limited in terms of archetypes (e.g. no ronin or ashigaru), but even so I still have several ideas I'd be interested in pursuing.
For example, I notice that the two samurai already signed up are both of the Crane -- would it be wise to submit another Crane character, or was that coincidence and other Clans are an option, too? Needless to say, both options would have their own advantages, one allowing more freedom, but the other a greater connection between the dramatis personae.
