"Jiuye was hung on a swaying tree and was stabbed by a spear; I was treated as Odin's sacrifice, and I sacrificed to myself, on a tree that no one knew! No bread to satisfy my hunger, no drops to quench my thirst. I went down. Look, pick up the Luen text, pick it up and shout, and fall from the tree." --- "Song of the Sage". Thus, Odin obtained the wisdom and mystery of Luen's writing. Luen is a kind of incantation, as long as it is carved on wood, stone, metal or even any material, it can get infinite power.

After randomly grabbing a single rune, provide basic explanation.

Because runes can be carried in any form, the energy of runes protects you. You can choose ᛊ when you want to have a smooth test, and you can choose ᚦ or ᚲ if you need some kind of protection. Guardians can also be selected in multiple ways. One rune has the effect of enhancing, activating or linking to other runes.
