No where in the links of the original post, besides those of player fiction, is the red god mentioned either. Which seems to be an important thing for Sani Sabik and Blood Raiders in the books. There is no mention of red god in-game as far as I can tell either. Please correct me if I am wrong.
Also, since we are on the subject of what EVE: Source has said about certain things. It also states that there is no need to believe in red god or anything supernatural to be Sani Sabik or Blood Raider. And as for bleeding children along side clones, it is said that all Sani Sabik must donate their blood to the Covenant for use in science, religious ritual, and for making blood-based foodstuffs which the Blood Raiders and loyal Sani Sabik subsist on for nourishment.
