DIABLERIE — [Noun] Witchcraft or sorcery, especially of a malevolent or devilish nature. From French diablerie, from diable ("devil"), from Late Latin diabolus ("devil"), + -erie ("art or practice of"). Unlike "wizardry" (which implies learned or skillful magic) or "enchantment" (which suggests charm or benign influence), diablerie is the art of the damned—a covenant with shadows. It is the flicker of candlelight revealing sigils carved in blood, the whisper of forgotten tongues in midnight chapels, or the sudden, sulfurous stench that lingers after an ill-advised incantation. A reminder that some doors, once opened, cannot be closed.
