Clean the wax out o' your ears now, 'cause there's somethin' I want you to do by way o' preparation.
The plan's to have you enter Castrum Centri all decked out in imperial duds, but a disguise is more'n just the clothes you're wearin'. You also gotta act the part.
At the very least, you need to know how to perform a convincin' imperial salute. First impressions're everythin', as they say.
I could teach you the salute myself, o' course, but it's best you learned it from the experts. So get yourself near as you dare to Castrum Centri, an' watch the imperials doin' what they do.
