Hospitality and guest rights plays an important role in Scandinavian culture. However, in my hours of googling I have only found one source that gives it a name: 'frið' or 'friðr'. Here's the source. I can't seem to find any other online sources that speaks to hospitality directly, and my library doesn't seem to have any editions of the Edda that show both the English translation and Old Norse original.

Can someone point me to sources that may help shed a little light?
