When msawhat corrupts qi, the energy of life, pravum is created. Pravum is the perversion of life, a form of undead energy that violates the law of life but not death. Quite simply, it affects natal and pre-natal beings. That which is not born is not alive, so cannot be dead, cannot be considered in violation of the laws of death. So violating it means only violating the laws of life, and that means creating pravum.

To be clear, abortion is not a violation in and of itself of the laws of life. Though pravum is often created by unscrupulous predators who perform dark abortions in places where safe and accessible abortions don't exist, this violation exists because of assaults on (pre-)natal care.

The methods of harvesting pravum from violations of the laws of life include but are not limited to

• forced abortion
• child-eating
• child molestation
• intentional, malicious alteration of the child in the womb or shortly after birth
• child abuse

It is considered one of the evilest, foulest arts, and those who practice it are even hated in some of the most vile countries.

The arts of pravum:

• Bone Knife, a knife made from the leg bone of a small child - drab cutler
• Pedophagy, eating children - pedophagists
• Corrupting the Innocent, corrupting or molesting children - drab pedophiles
• Ars Pravum, alchemical use of pravum - drab alchemists
• Malmedica, using pravum in children's medicine - malmedicinists
• Worm Harvest, filling a child with pravum-filled worms - worm-harvesters
