@Bennia pawn was using the fact that Zeoticus's bishop Heinrich Cornelius Agrippa died in February 1535. Considering this the evil piece system is around 500 years old.

I would prefer if Issei ends up with 4 to 6 pawns but we don't know if maybe Issei has mutation pieces that haven't been mentioned yet because all his peerage originate from trades.
