Culture plays a very important role in day to day lives of everyone in the Empire.
An example of a full name is Velvok ir-Ihhliae tr'Vaebn. Only his Housemates and those to whom he gives special permission may call him Velvok. So if someone tells you to go find tr'Vaebn and you don't know which tr'Vaebn it is, you must assume that you are supposed to find the hru'Hfirh of s'Vaebn. The cityname and rehei are rarely used. He would never publicly reveal his rehei with anyone except his wife and perhaps his children, since it was chosen during a very special point in his life and probably carries special emotions with it.
