And in a purely material world there’s plenty to believe in, blood being an obvious one. (While I’m not one any more, I understand my old world well, I converted due to some non-athesitic/agnostic beliefs I held (mainly my ideals being a universal truth and a hunch we’re wholly distinct from beasts) and my general thought process lining up with Armanism once my fren explained it to me when I was curious)
Edit: Asides Armanism gave us the Armanen runes and Die Schwartz Sonne so there’s that too lol
