Hello there, allow me to share a personal observation after three decades as a wanderer in the world of magic. While the dark arts encompass a chilling spectrum, ranging from abducting children for immortality to hunting strangers for body parts, or even using people's organs for monetary gain and manipulating minds through spiritual manipulation, what truly stands out among the thirty-six nefarious practices is the sinister force within human nature itself.
These practices, involving blood, flesh, and lives as mere tools, often involve inexplicable terrors. But my experience has taught me that, at the core of it all, the gravest evil isn't the art itself, but the capacity for humanity to embrace and wield such darkness.
