The Whiterun people have complained about 2 very annoying people - Braith and Nazeem. So, 11 guards were sent to make those 2 bastards pay for their crimes. From now, every time one of those 2 will walk on the streets, the ebony guards will beat them up until they ask for mercy (and after it as well).
