The royal seal was a vow that members of the Elder Houses had to follow. Any item placed under the seal had to be kept secret. If the vow was broken, the ruling council of the Elder Houses had the authority to strip whoever broke the seal of all of his or her titles. During the time of the New Republic, Lady Carise Sindian broke the vow when she released a private recording and was stripped of all her titles.
