The Council of Clan Elders, commonly shortened to Droghi Council, convenes in the Council Room at regular intervals to review the major business of The Nine Systems, including handle such matters as trying major criminals (including an oddly prodigious variety of cheaters), hear and discuss future policy decisions, and safeguard the transition of power (see Leadership Challenge for more information on this particular role).
The Droghi Council is a more-or-less flat team structure given as it serves as the intermediary body between the Leader and ranked officers (as well as the rest of the Stenza population). However there is a somewhat informal system which gives greater weight to the voices of the oldest members of the council (at the moment one such person is Creyth, currently the oldest living Stenza).
The Droghi Council is populated by opinionated individuals, and is therefore prone to legislative violence (this is commonly exacerbated when they serve under a highly controversial Leader and know it). However, leaders who are willing to meet them as equals and hear out their concerns are able to reduce the number and severity of outbreaks of violence.
The Council of Clan Elders was originally a much broader group including ranked officers and top scientists of various sorts, all convened by Iradae the Lawgiver in order to help deal with the Stone Menace. They were also instrumental in cementing the early governmental structure of the nascent Stenza state, before the council was narrowed down to just clan elders to separate the responsibilities of officers from the leadership of the society as a whole.
