Christianity can also be a way to bring about moral conflict. In the Imperium, which has its own set of beliefs and dogmas, a character following Christianity might be seen as a heretic. Fanfictions can explore how these characters navigate this tricky situation. They may have to hide their faith while still trying to uphold its values. It could also lead to interesting interactions with other religious or non - religious characters in the universe. For instance, a Space Marine chapter might be divided between those who see the potential in the Christian faith and those who see it as a threat to their existing order.
Some fanfictions might use Christianity as a tool for redemption. A character who has committed many sins in the brutal Warhammer 40k world could find salvation through their Christian faith. This could be a powerful arc, showing how the values of love, forgiveness, and repentance can exist even in such a violent and unforgiving universe. It might also show how their new - found faith affects their relationships with others, like their comrades in arms or the civilians they protect.
