I was wondering, how would your basic Imperial worlds react to say a wondering Eldar group....or a Tau loner on his own? I'm sure it's not like Star Wars where it's very common to see other races...in fact I'm guessing it's very rare. But What is the tolorance level? Would they be killed on site, or arrested or left alone but looked at with hate? Would it depend on what world they were on, or is there some sort of Imperial code that you must follow when encountering a non hostile alien race such as Tau, Eldar, Kroot, etc.
