Religion (Halo Setting)
From D&D Wiki
The Covenant, being a theocracy, is both a nation and religion. It centers around the worship of the forerunners. When the san’shyuum unearthed a Forerunner dreadnaught on their home world, the data banks were poorly translated. The long undiscovered texts told of the plight of the forerunners, but they read it as the guide to their transcendence. They believe that the activation of the Halo rings and the collection of artifacts will lead to a perfect eternal life. However, as humanity is the foretold holder of the Mantle of Responsibility, the san’shyuum began the great war in hopes of stealing their birthright.
Triad is a human religion founded by the self-proclaimed guru Dasc Gevadim. The followers of Triad believe that everyone harbored three internal lives, and believed one can reach spiritual "transcendence" by linking the three.
The founder Dasc ran many seminars through video feeds until he disappeared. These videos received many purchases and the religion gained millions of followers. When Dasc disappeared, many believed he had reached transcendence when in reality he had left to Beta Gabriel under a false identity. During the Jiralhanae occupation, he was captured and placed in captivity. He managed to escape with UNSC linguistic expert Connor Brien, however he felt that he could not let the secret of his continuing existence be revealed. Thus, Dasc killed Brien with his own M6 sidearm and hid from the UNSC reinforcements which arrived soon after, preferring that one man die so that the faith of millions could be preserved.
Due to the lack of longevity among A.I, often only living a decade, most of not all A.I. believe in a form of Zen Buddhism, with Koans, spiritual questions for meditation, being popular sources of intrigue.
Never formally given a name, this ancient religion was polytheistic, based on the belief in Precursors, god-like creatures with the power to travel intergalactic distances and accelerate the evolution of intelligent life. It is implied that the forerunners believed the Precursors had given them the Mantle of Responsibility, a source of forerunner authority, and believed they would later give it to Humanity.
