TriviaEdit

• "Ecumene" is a word describing the earth as known by the classical civilizations of Greece and the Romans. This later became used by Christian denominations to refer to the general "Christian world".
• Even though the Ecumene council could number in the hundreds, there seems to be three main speakers; the Didact, the Librarian and Faber, who represent the Warrior-Servant caste, the Lifeworker caste and the Builder caste respectively.
