The Unnatural Acts were written by King Duncanthrax on 9 Dismembur 672 GUE.
They provided stiff penalties for those convicted of selling "Unnatural or Supernatural substances". The motivation for this legislation lay in charlatans who regularly fooled the gullible population into buying potions which claimed to do such things as "reverse hair loss" and "draw Trebled Fromps in Double Fanucci".
The restrictions of the Unnatural Acts were eventually loosened, allowing the foundation of the first chapter of the Guild of Enchanters by the great thaumaturge Vilboz.
