The Temple of the Triune was a cult that existed during the time of the Sin War. Whilst outwardly a benevolent religious body, in reality, it was formed by the Prime Evils to convert humanity to their side.
The Triune rapidly fell into disarray after the mysterious disappearance of the Primus. In the end, by the combined efforts of Uldyssian and his nephalem followers, not to mention Lilith herself, the Triune was utterly destroyed.
Despite this, the Triune survived even into the modern day. The cult's remnants eschewed the cult's benevolent facade and operated in the shadows, preserving their order's secrets, awaiting a sign from the Prime Evils. The Coven formed also as a splinter group of the Triune. It is considered likely by Tyrael that other splinter groups also exist.
The Triune had temples in various major settlements, mainly in the eastern regions of Sanctuary. Each temple was subordinate to the main temple near Kehjan. The Grand Temple was a sprawling, triangular edifice with three high towers, each situated at one of the points. The pinnacles themselves were three-sided with each face marked by one of the holy orders. Triangular windows lined the towers from bottom to top. The entrance could be reached by ascending three levels, with each level consisting of thirty-three steps. Three bronze doors had to be passed in order to gain entrance to the temple's interior.
The Triune consisted of three smaller cults, each devoted to one of the Triune's three guiding spirits, which were in truth the alter egos of the three Prime Evils. All three cults were lead by a High Priest from the main temple. Other, lesser temples were generally led by a senior priest or a band of lesser priests. The governing authority and leader of the Triune was the Grand Priest - the Primus. Peace Warders, cowled guards who wore the symbols of each order on their chests guided newcomers to a cult of their choosing. The demonic morlu served as an elite fighting force, only deployed in special circumstances.
The three guiding spirits were named after the Prime Evils themselves, and were titled with exact opposite of the aspects of the Prime Evils. Unsuspecting initiates were lured into the cults, fooled by the seemingly kind guiding spirits. Gradually their hearts would darken as they were initiated into the true teachings of the Triune, and the true spirits they served. The three guiding spirits were known as Dialon, Bala and Mefis, and each had their associated order.
Order of DialonEdit
Dialon, Spirit of Determination, was represented by a stubborn ram. Dialon was believed to bring Purpose to humanity. Statues of Dialon were usually depicted wearing the Tablets of Order, which taught how to achieve blessedness. In truth, followers of Dialon served the Prime Evil, Diablo, the Lord of Terror.
Order of BalaEdit
Bala, Spirit of Creation, was represented by a leaf. Bala preached the blessings of nature and the architectural triumphs of humanity. Statues of Bala were usually depicted wearing a hammer and a bag, which presumably contained the seeds of Life. In truth, followers of Bala served the Prime Evil, Baal, the Lord of Destruction.
Order of MefisEdit
Mefis, Spirit of Love, was represented by a red circle, the Kehjani symbol for the heart. In a sense Mefis was the most crucial of all spirits, as the Primus taught that Creation and Determination could not thrive without Love. Statues of Mefis were depicted with empty, cupped hands, as if they were cradling an infant. In truth, followers of Mefis served the Prime Evil, Mephisto, the Lord of Hatred.
