Old Norse: Rísi Anglo-Saxon: Hrisi
Risir are benevolent spirits of natural places like lakes, hills, and rivers. They are a type of giant described as fair to look upon and not to be much greater than human stature. They are said to be of low intelligence though and like throwing boulders at each other. Generally, however they seem helpful to Mankind, but due to this low intelligence that usefulness isn’t much good.
Berg-risir is the specific name for mountain spirits
