Courier duty in the Guard as a whole was considered pretty 'low' work, being usually little more than shuttling notes from one snooty officer to another. But VIP Courier duty, on the other hoof, promised a wealth of excitement! Rushing important government documents to members of the Court! Fetching great tomes from the depths of the most arcane libraries! Rescuing their VIP from social situations with quick deliveries of important sundries! Maybe even... delivering a romantic letter to someone your VIP admires? Sealed with a kiss, of course! Oooh, the idea of that last one got her giddy like a brisk sun-shower.
