The Empyreal Assembly, formerly called the Priests Guild, is one of the oldest organisations in Achaea, although the details of its formation is mostly lost in history. Along with the Templars (more recently, the Paladins guild and presently the Guardians of Light), the Empyreal Assembly forms one of the two major arms of the Church of Achaea. Originally housed in Delos, the Guild and now House moved to Shallam when the Church successfully petitioned Sarapis to move the Basilica to Shallam. In the Modern Age, the Priests Guild was founded by Odysseus in 178 AF. The Guild became a House in 396 AF. The organisation is devoted to the tenets of Honour, Service, and Wisdom as well as the ideals of Order, Righteousness, and Light.
Originally, only those of the Priest class were allowed to join. However, in the year 403, they began to allow membership to those of the Paladin class. They have gradually increased the number of allowed classes since that time. The skills of the Priest class evolved slowly over the history of the organisation, developing after specific events and derived older practices. The skill of Spirituality, for example, was gifted to the ancient Priests by the Hierarchs of Celestia after being judged worthy of having angels as guardians. Devotion is derived from the ancient Rites of the Holy Church and exists today as more a compact version of the older one.
The Empyreal Assembly's House tutor is Marhisa, Priestess of Virtue, who resides in the Chrysalis Basilica in Shallam.
