Ok, looks like the majority want Rank 2, or are happy with either, so I'm going to say go with rank 2 characters. You can assume that at least part of the time between the rank 1 and 2 was spent training for the role of magistrate / yoriki, and can take skills accordingly.
Muse, check your PMs and get back to me if you need anything more.
So need to build this in to the character build.
Unless someone wants to volunteer themselves, we can sort one out for you. Hiring a ronin as a bodyguard would cost 1-2 koku a month, depending on how good the bodyguard was.
The Magistrate receives an annual salary of 100 koku (1 koku being the ammount of rice it takes to feed a peasent (family?) for a year). Each koku can be divided into 5 silver bu, or 100 copper zeni. Magistrates are expected to pay their own retainers out of that.
Next question is I have. Is those that are emerald magistrates, do we have to take the advantage social position 5pts or is this assumed. An thus given for free.
Neither. As a duly appointed Emerald magistrate your status is 4.5.You'll outrank pretty much anyone other than nobility and similarly important people.
