Rune Symbols, in Norse mythology, were the mysterious characters that Divine King Odin obtained by sacrificing himself to himself while hanged upon a tree.
Self-sacrifice might sound illogical,, yet as a deity, Laine had come to a deeper understanding of it.
The one offering the sacrifice was 'Odin', yet the recipient was also 'Divine King'. The present self was sacrificing to the future self, with Odin as a deity making a sacrificial offering to the world; and what he ultimately gained were the Rune characters, which contained the secrets of the World Tree's origins.
Although as text describing another world's Law, Rune Symbols might not be as effective in Chaos World, Laine was more interested in their principle of existence.
