In the Northern Realms, there are 3 main interpretations of the law:
Erenian Standard Law, a law code written at the Founding of Erenen and adopted by many other countries, such as Gandortal, Aregrionno, Helladris, Dorion and Ashar, albeit with small variations.
Northern Law, as practiced in Imland and Norfell, which is more lax in some fields, and more harsh in others.
Dorwinian Law, which implements long sentences and capital punishment.
