Keysshi was the name of the ancient Twi'lek ceremony of History. It was a public ceremony in which a clan celebrated and shared stories of the History of the Twi'leks and in particular, the history of the clan. This ceremony was used as a means of passing down tradition prior to written language. Tales stated that the ceremony was presided over by a crystal skull carved from the crystallized ashes of the Jedi Lord Newar Forrth, ruler and protector of Ryloth during the New Sith Wars.
