The Reinheitsgebot is an ancient Wesen purity law which states Wesen may not marry outside their race. Today mixed marriages are still a taboo, and radicals in the Purewelt Orden perform bloody demonstrations against offending couples, their families and supporters.
- The Reinheitsgebot (literally "purity order"), also known as "German Beer Purity Law" was part of German law from April 23, 1516 until 1993. It states that the only ingredients allowed in the production of beer to be water, barley, and hops. The revised law now allows for the use of yeast, cane sugar and wheat. All the ingredients are subject to strict regulation.
