The Grand Archwarden is the highest office in the Communion. Once elected from the priest caste, they will remain in office until they die. They live in The Great Nemeton of Tremadon where they hold weekly ceremonies for the hundreds of pilgrims that make their way to the shores of Lake Tolos. On rare occasions, the Grand Archwarden will travel to other parts of Northern Tarania to visit a sacred grove or to carry out a ceremonial duty. The Grand Archwarden is protected by an elite group of Grey Cloaks.
