The Ferdiad Cycle
The high king of Aenoria and the fifteen thanes gather with their closest advisors by the sacred standing stones of Gwynnaghl every four years in a meeting called the Conclave. It is an ancient custom reaching back to the tribes of old who first gathered together to try to stop the invasion of the Ellysians almost a millenia ago. The meeting has many ritualistic phases after the chief sit at a feast to contemplate the coming four years. Spilling blood at the site is prohibited by the highest law and anyone doing so is condemned to exile.
