Valac or Volac appears as a cherub riding a two-headed dragon, and can tell its summoner where to find either serpents or hidden treasures. You’re not alone if you can see some potential problems there. Recently had a star turn in The Conjuring film franchise, being (as “Valak”) the entity possessing The Nun, and, like many of these antique demons, shows up in either the Castlevania or Bloodstained games as a monster.
