The Rhash'm has to make public appearances together with the Emperor in every event and occasion in and out of the Empire.
A Rhash must go to all length to safeguard the life of the Rothaur. He will taste the food for the Emperor first to detect poison. He will put his body before the Emperor before the assault of an assassin. He will handle every article that is presented to the Emperor before it was in the Emperor's hands. He will obey every command of the Rothaur no matter the consequences. He is to devote his entire life and affection to the Emperor.

They are taught embroidery and tailoring so that they could make clothes beautiful enough to fade behind the glory of the Emperor. They are taught to sing all the ballad there is in the Empire and to dance from the graceful sworddances to the sophisticated loredances. This is so that they could entertain the Emperor and sometimes his guests, and the Rhash'm are famous for their mastery in song and dance throughout the world.
