... or something like that.
Or can't you just drop a new and mysterious (and maybe heavily armed, or maybe not) stranger into any town (or any other location) in any background at any time for any reason - especially the type who rides in alone (or with company) on a horse (or other mount, unless he walks, or arrives on a ferry, or airship) looking mean (or looking for trouble, or not looking for trouble but ends up causing it, or not looking mean or troublesome, maybe he looks sick, or the type that.. etc)
Its more a DM thing and a campaign style IMHO - look at how many westerns are actaully based on samurai stories, or Shakespear, or old legends or myths or folk stories or whatever.
In the end its down to the DM and the campaign - is it about duels, personal and family/clan honour and owing people duty and or debts, and facing responsibilities and insurmountable odds because its expected of you, or have you got a prior appointmnet in the kobold caverns killing the occupants and taking their stuff?
