How much can you bend the rules? Can you make the game do all the testing, then just get someone else to add in the music?

I read one of your comments about Paganism too. It's not really about people that worship the devil, it's more just people that don't worship your god/gods. Could you find an instrument that originates in your country/religious group?

It's kind of a historic term too so could you maybe use Synth music, the synthesizer was invented in 1952 in the US.

If none of that works, just use world noise. Footsteps, rain, water dripping, birds etc
