There are two major “religions” followed by the Quarians. 

          One is the belief in three powers: a synthetic god, & two Quarian gods. This religion, often referred to as ‘The Three Divines’, holds a representation of machines, man, & a higher spirit. The female Quarian, known as ‘The Mother’ (which is often related to the central Goddess of the Asari religion), had a son, who created a synthetic life. This is the only solid knowledge of the religion all Quarians share, as there are different stories about each which different clans & ships adopted. Now mostly a dead religion, most refer to The Mother, who was seen as an almighty creator & a balance between organic & synthetic life, in prayer while in battle or working. 

          The second religion, a much rarer occurrence in Quarian culture, involves the idea that every synthetic being has an essence, or soul, which came from an organic life sacrificing itself (usually represented as a female) for the sake of saving the galaxy, in turn, due to the orangic’s purity, giving everything a soul that makes everything capable of several principles & the ability to follow a set “code” made by the sacrificial being. This religion was mostly practiced before the creation of the Geth, though some, who believe in peace with synthetic life, still practice it. There are set principles & a moral code that must be followed, but specifics are unclear. It is believed that the sacrificial organic had several prophets that built temples on Rannoch, & are reborn within each generation. Due to this, followers of this faith are eager to return home to further investigate. 

          Mostly, however, Quarians do not follow a set religion or philosophy, but share a basic desire to be loyal & learn. There are other religions of course, or variations of the major two. Some Quarians revert to other religions of the galaxy, specifically the Asari religion, as it closely resembles their own. However, religion has impacted their culture, as purple & red are seen as sacred colors, & genders represent a role in their core beliefs: females are creators while males are warriors, but they are both equal. Females are seen as pure, powerful, & mysterious. Males are seen as protective, moral, & peacekeepers.
