Kaidon

The Kaidon (or "Clan Leader") is a Sangheili meritocratic rank. The head of a Sangheili State is referred to as "Kaidon". Kaidons are chosen by Elders of their State. The Sangheili "Clan Leader" seems to be more of a political position than a military position.

Overview
After crowning, it is considered a tradition that any elder who disagrees with the crowning of the new Kaidon send an assassin to kill him or challenge the Kaidon himself, as a form of testing whether the Kaidon is worthy of ruling. Should the assassins fail, the sender is most likely executed, as was Koida 'Vadam, the elder that attempted to have Thel 'Vadamee murdered. However, if the Kaidon is killed, no action is taken against the Elder, as the Sangheili believe that a Kaidon who cannot defend himself is unworthy of leadership.

The Kaidon, despite being a political ruler, is still very active in the military, even leading long time campaigns into enemy territory, leaving the elders to rule in his stead. Kaidon is a life-long rank, so the next Kaidon is only crowned after the current Kaidon dies.
