aight so it is speculated that the septagram/heptagram used on papa iv's robes is likely a tribute to alchemy. the only trouble with this is that the symbol is clearly inversed. i haven't seen anyone talk about how this could have a double meaning and relate to christianity too

there is a 7 pointed star in christianity which represents the creation. it is obviously a big part of the faith. copia's theme since day 1 has been death... so, if you were to inverse a star representing creation, wouldn't it mean it's a symbol of destruction?

if it is, i think it is an important part of the lore that would tie ghost's traditional theme of devil worship with the theory of necromancer papa iv. he is creating life through the dead. the irony of copia being a murderer who also brings back dead papas is not lost on me lol
