Runes originally meant secret wisdom because few people knew them and lacked the ability to use them correct and the invention was believed to come from Odin. But in reality they were a modification of the Roman Latin alphabet, but made specific for writing on wood, B and R were to round to be written on wood. There were original 24 signs but they were later reduced to only 16 signs. In the heathen viking period, a superstition meant that people believed that runes could be used for sorcery and have a supernatural effect, where they were made. Strong runes and wooden sticks, had secret powers and could silent the enemy's weapon, create storms and stop storms and bad weather, stop fires, shape shift people, predict future and summon spirits.
