Trel, Karl, Herse, Jarl, Könge

Trel, Karl, Herse, Jarl, Könge
The basis of the martial art is the use of five principals which are related to the five "classes" (Trel, Karl, Herse, Jarl and Könge) and five elements (Earth, Water, Fire, Ice and Wind) but in addition to this the use of sixteen postures and associated breathing techniques and "incantations" (called "galdor"). 

The sixteen postures are used to make the body form the shape of the 16 runes of the futhark (in the variation used by the Hosling).
